Proper USB GameCube Controller for use on Dolphin

[12GaugeRabbit]

(This is a controller-related thread, by the way.)
12GR again, and earlier I got a USB Controller shaped like a GameCube controller, but however this didn't have analog triggers. I would have tried to return to the seller but I just would leave it alone. So, my question is, could you give me any suggestions on the proper USB third-party GameCube controller for use in the emulator?

I would recommend a real GC controller and a switch/wiiu adapter, you're probably not going to find any good USB 3rd party controllers.
