Snes to USb convertor

I thought I'd buy one of the USB conertors to play my Snes emulators with an Snes controller. What would be the best convertor to use? I also use windows vista.

I don't know specifically who sells SNES converters, but if you have a Playstation 1 or 2 gamepad, you're better off getting one of those converters. The PSX controller is practically the same layout as the SNES except for analog stick options, and the extra set of L/R buttons. Plus you'll have a few more button options for a wider variety of emulators or PC games.. Most converters can be had for between $15 - $20.

www.estarland.com sells PSX/USB converters.
