I've got a converter that lets me use a PS2, Gamecube, or 360 controller on my PC.
It's really nice, and for the first few months I owned it, I thought it was the best 10 bucks I ever spent on a peripheral for my PC...but it eventually fucked up my PS2 controller to the point where I cannot press left or right on the d-pad anymore (it won't even work correctly on my PS2), so I suggest being extra careful before prolonged use of such an accessory. Nowadays, I always unplug my controller from it before powering on/off my PC...hoping this cautiousness is enough to keep that from happening again.
