Ok... finally off work.
First... I looked at trainrider06's suggestion again... he overlooked mentioning you'd need an eGo style charger... they aren't much more than what he mentioned but when you add up the things he did mention ( battery, Mini Protank 3 and extra replacment heads/coils ) you end up over $56 ( the replacement coils are about $8-10 per 5 pack ) and you didn't get a atomizer with airflow control which can help in several areas. In short... you can get better for about $50 if we are talking about almost the same setup but with a few improvements.
First... let me cover some details and give some info about vaping in general. You don't have to know this but I feel it helps when you understand some of it... there is no test at the end
Types of e-cigs... There are about every type you can imagine and more. For some, this makes it seem confusing but it shouldn't. I'll briefly mention that I'm not going to go into the more advanced types with one exception which is going to be one of my recommendations...
-----------------------------------------------
The cigarette sized mod's or stick types... are what you'll see around a bit in convience stores ( ie 7-Elevens etc ), gas stations and even Walgreens and Walmarts for that matter ( if they are allowed to be sold in those in your area ). Some have rechargeable batteries and some are disposables. None of these are good replacements for ciggies in my opinion. They are too underpowered to provide good vapor. Trying one to see if vaping may help make be ok... but don't expect to be satisfied much by them... they can only give you an indication at best. The more accurate names for the two common sizes are 510 and 808 types... the numbers refer to their size in millimeters of their casing and connection type, just so ya know.
The ones that really start to work ok are the eGo styles, similar to the one linked earlier. These come in various battery capacities ( MAH ) and the bigger the capacity the longer you can use them before they need a recharge. Standard versions have a fixed output voltage of 3.2v-3.6v... the more voltage the more power so you can end up with a more satisfying vape.
The next step up from a standard eGo is a VV eGo type like what was linked earlier. These allow you to adjust the voltage output between about 3.2v-4.8v. When you increase the voltage.. you increase the power ( wattage ) which allows you to make more vapor and/or have a stronger or richer flavored hit. When adjusting these, you need to take the resistance ( Ω ) of the coil head you are using into account so you don't burn out the coil. Using Ohm's law will allow you to calculate what your output power is in watts.
There are also eGo types that make it a little simpler... you just adjust the wattage you want directly without having to consider the Ω of the coil as much. These are hard to find.... so I'll just leave it as a brief mention.
Then there is the next step up, and one I'd recommend to anyone even a beginner if they are serious about it... The VV/VW advanced mods. They are referred to as advanced not really because they are harder to use... just because they give you more options. In fact, I find that adjusting a VW setting much less complicated than a VV type simply because you don't need to calculate your power output... it's done for you based on the resistance of the atomizer you have on top.
Now that briefly covers the various personal vaporizer batteries... hopefully without overdoing it too much. Next are the types of atomizers that go on top of the battery, hold the e-liquid you are vaping and contains the coil and wick that is used to vaporize the e-liquid.
-----------------------------------------
The basic one is the clearomizer. They are a self contained unit that you fill with the juice you've chosen ( as with all types now ). These don't have replaceable coil heads in them but once they are used up and can't be cleaned anymore... you just toss them. These, like all atomizers I'm mentioning, will come in certain resistances... lower resistance coils will output higher wattages but also use up your batteries faster. Higher resistance coils can help your battery last longer but it also limits the power ( wattage ) output so there won't be as much vapor/flavor/strength of hit etc. Having a VV or VW mod can allow you to adjust for the resistance Ω of the coils you choose.
The next step up is like the Mini-Protank you were linked to. It's just like the basic clearomizer but it has replaceable coil heads which help keep your costs down in the long run.
Another step up from the one's like the Mini-Protank also allow you to adjust the air flow you get. You can increase the draw which increases the flavor you taste... or lessen the draw, increasing the air intake and which helps make more vapor. This is the type I'd recommend now over the Mini-Protank... Kanger makes one with a similar size called the Mini Aerotank and the flavor/vapor you get is much better in the end than the Protank version because you can adjust it to suit your own preferences more.
Then there are the more advanced types of atomizers... tanks, drippers and various others. You can learn about these later after you've found out if vaping is the direction you can go in.... In fact, with the right combination of vape supplies, there is little reason that you can't find something that works for you.
-----------------------------------------------
The last part that I'll only touch on... the e-liquid itself. These come in so many flavors, NIC levels and PG/VG ratios it's mind boggling. Trying to recommend one to someone without a good knowledge of their preferences is near impossible. I will say this... taste is subjective and everyone will have their own opinions and favorites... One person will say something tastes like crap and another will absolutely love it. If you get one you don't like... don't sweat it... there are plenty of great tasting ones out there... finding them just takes a little time.
The stuff that makes up e-juice is easier to cover than the flavors.... so I'll do that now. The base juice used in these ( besides the added flavoring ) is PG and VG. This is what is being evaporated into water vapor and carries the flavoring that is added. They don't always contain nicotine but most will since that is what most people are trying to satisfy their craving for. The PG is the thinner of the two types and carries more flavor than the VG will, it's also going to be the part that gives you more of a throat hit than VG will. VG is the thicker liquid and contributes more to the amount of vapor and how thick that vapor feels to your throat and lungs. The two most common ratios of these are 80PG/20VG or 70PG/30VG but sometimes they vary depending on the company making them.
Both PG and VG are found in many of your common household and medical stuff. They are used in medicine such as liquid capsules... as well as many other liquids you commonly use around the house like shampoo, conditioners, hand lotion and many other things. These are already FDA approved but some people can have a sensitivity to one or the other. When you first start vaping you may actually find yourself coughing more than normal... this is actually normal most of the time... The water vapor that these are vaporized into also starts breaking up the tars you've developed in your lungs. If you have other issues that you start noticing... ask around about them just to see if you have a sensitivity you were not aware of before. If so... you can switch to a more PG or VG heavy juice.
Ok... that should be a good overview of the stuff. I know there is a lot I left out but it will give you enough info to help make smarter choices that fit you better.
---------------------------------
For a basic starter set that just gets you in the door but doesn't have the things I'd recommend as much... It has a basic eGo type battery ( not VV or VW, charger and an Evod clearo that can use replaceable coil heads. This costs about $16.00
KangerTech eVod Blister Pack - Sun-Vapers.com
The next step up, and what I'd recommend instead of what trainrider06 mentioned ( it's more complete and a little cheaper ) ... it has a VV eGo battery, with a EMOW clearo that has adjustable air flow, comes with an additional 5 coil heads as well as having a charger you'll need. This costs about $50.00
Kanger EMOW Mega (Starter kit) - Sun-Vapers.com
Another kit that I really like... it has a more advanced battery that is VV/VW, the battery is a smaller height so fits in your hand better, it has a top of the line clearo tank with air flow also as well as a 5 pack of replacement coil heads, charger etc ... It costs about $80

On all kits... you'll need to choose a juice to start you out with. I'd guess that a 30ml size bottle will be about equivalent to a carton of cigarettes or there abouts. At some point you'll need replacement heads that are compatible with whatever you choose... expect each head to last around a week but may last longer depending on which juice you select. Note that some juices don't clog a coil as quickly as others... so that is just something to judge it by until you know how the juice you select will be.

PS....
I forgot to mention something... of course
The various coils that both of us mentioned... each have their own voltage/wattage recommendations for them. The Kanger coils all come with a sheet that list their recommendations. Exceeding those recommendations risks you burning a coils up before it's expected lifespan. So try to not exceed those settings.
If you get a VV and/or VW mod, some people think it's harder to use than it really is... start at a low setting and adjust up until you like it... that's it... Of course, you still don't want to exceed the recommended settings for a specific coil if you can. Most are under rated, so you do have some wiggle room if needed.
When you first fill one of these... whatever you get. Let it set for a few minutes or so. This lets the juice soak in so you don't burn up the wicking. A burnt wick can't be fixed... it'll taste bad from now on.
E-liquids also can be set too high and taste burnt... if you do this, just turn down the voltage/wattage. You didn't ruin it... just turned it up too high for that particular juice or flavor.
