I was able to get the PS2 controllers at a discount at $8 per controller. If you can link me to better and more affordable ones, I would love to see them. Keep in mind this was self-funded, so we had to make a lot of compromises to keep things somewhat affordable.

I use one similar to this: https://hobbyking.com/en_us/hobby-king-2-4ghz-4ch-tx-rx-v2-m... . About $28 and includes a transmitter, joysticks, and the receiver. Most fighting robot builders using this setup don't need an Arduino, breadboard, sensor shield, any additional boards or configuration on the transmitter side, etc.

Thanks for sharing this. That would have cut down on costs for sure.
