For running games on PC, I have found a couple of USB SNES controllers. They're perfectly fine for casual play -- but I've run into an issue where the Up arrow on the d-pad is overly sensitive at times, and just pressing Left or Right can trigger an Up-Left/Up-Right instead https://mobdro.onl/ https://vidmate.onl/.

What I'm wondering is, what good controllers have the folks here found, especially on the inexpensive side? I mean, I like to keep my options open, but I'd also like to avoid dropping another $200 on a controller (coughstupidTGMpracticecough).

highly recommend staying away from most usb retro controllers and to get adapters for original controllers instead.

You could look into 8BitDo’s controllers. I haven’t tried any of the retro-style ones, but I know they’re well-regarded.
