Best Cheap Stick Transmitter

[X - Racer]

I am currently looking to purchase my son a cheap stick transmitter and receiver set. He currently uses a Sanwa Gemini X Transmitter which needs replacing.

I was looking at the Core CR151 transmitter and receiver. Are these any good? Or does anyone use one and can give me some feedback please?

Is there any other brands of stick transmitters out there, which are not expensive and come recommended?

Thanks in advance.
