Help - newbie requires cheap controller for G2!
 

I'm a bit new, can anyone help me?
I've had Realflight G2 for a few days (I really love it) and want to learn to fly a heli. I'm currently using a 2 joystick gamepad which works, but I'm told a proper transmitter would be better. I don't doubt that, but the question is: what to get?
I don't plan to get a real heli for at least a year or so - I want to learn on the sim, and am quite cautious so don't want to buy anything until I'm confident I won't crash on every flight.
When I do buy a real heli I'll probably buy a micro electric heli, fixed pitch, so I think I would only need a 4ch tx.
I think I can either get:
1. A buddy box
2. A real transmitter
3. A game commander.
Can anyone advise?
Cheers,
Matt
