I have 0 good things to say about BH, xheli, hobbyking or any of them. I just destroyed an HK450GT Pro because I don't want anyone else on here to be cursed by chinese crap. I'm done buying cheap crap and if I can't afford something good that I know will work, then I just won't fly. I will not put my family or friends in danger because I wanted to save a few bucks.
I have seen the DX6i that Matt has and it's a good one. I have not checked the numbers, but it's directly from horizon so I assume it's a good one. The next best thing is the DX7s and the best for what you are doing is the DX8. There is a DX18 but it's far above what you are into right now.
The DX8 is $430 shipped from horiizon if I remember correctly. I have mine for sale for $415 shipped with the AR8000 Rx with the telemetry module and all associated wires that it came with. DX6i or DX8, you can get both right here from the forum either from myself, or Matt, it just depends on what you want to spend.
