You'll probably have more success in gathering the info you want if you provide a price-range. I'd define the low-end of the mid-range as the seven channel setups, with the high-end of the mid-range to be the nine and ten channel setups. Everybody is going to define that range a bit differently.

You can't really go wrong with any of the Airtronics/Futaba/JR/Spektrum gear in that range. Consider the features of each, the available receivers, how the unit feels in your hand, and whether or not you "get" the programming for any particular type. Do those things, and you'll figure out what is right for you.

Pick your price range, evaluate the systems available within it, and pick the one you like best.
