Well maybe a DX6i or 9x, the problem with these radios is that they lack feature support that make models easy to setup if the radio is good enough and mostly settings can be done on the cheaper radios but usually with a fair bit of faffing around, best to just not go there.
I have said this many times and I will say it again, the best money that you spend early on in this hobby is to buy the best radio you can afford, if you cannot afford at least a resonable radio then you are approaching the hobby the wrong way and will have many tears. If you need to wait then wait and save your cash and then buy a good radio. No good will come of it if you cheap out on a radio and it is hard to use, hard to program and then fails at a critical point in a flight.
So a DX7s, T8FG Super or non Super (firmware update makes them the same) or Taranis should be the minimum you should look at if not them half of the hobby you will have chosen is to get you radio system working as easily as the rest of us already enjoy. It is fine to buy used, bought a Futaba T8FG used for AUD$200 delivered for my second son to replace a 9X that worked okay but what a pain to get it to do what you need it to do, great radio, FrSky receivers are available lots of places and are cheap and perform superbly well for the Futaba's.
I have a Spekrtrum DX18, Futaba 12SG and FrSky Taranis among other radios at the moment so have a bit of experience with them.
Cheers
