How to repair a Moga XP5-X+, or suggestions for another controller

Hi,

I tried contacting PowerA about which parts I'd need to fix joystick drift and a sticky directional button, but they would not help.

It's a long shot, but does anyone know if the parts needed are available for purchase? I don't like making e-waste.

Alternatively, does anyone know of a good Android controller that can be repaired easily? (e.g. Something I won't have to make custom silicone pads for or otherwise get too technical.) Or should I just get a wireless XBox controller?

Thanks
