I have way too many radios, but have started to get rid of some of them now that I have my Flysky FS-GT5. It's priced far lower than your budget allows at $65, so there are higher end radios out there. For me, I'd use the extra cash to stock up on receivers for the FS-Gt5. Non Gyro RX are FS-a3 are $10 and Gyro version FS-BS6 are $20 each, you'd be able to use one radio for many RC's.
Sorry, wrote this before reading that you are flying planes. Anyway.. FS-GT5 is great for cars. For planes, I am currently using DX-8 but am moving everything over to the Radiolink Boxer, once it arrives.
