Bent Pedals is a nice, self-explanatory site. A few for sale (the one on the left of this pic is $150), plus helpful schematics if you want to do it yourself.

Well, the sound samples don't exactly make me need to go blow $150.00 on this, and thier schematics are colored circles on a picture with no commentary. You'd be better off going to TonePad or the like and just looking at a real schematic.
I've personally bought a few pieces off Bentpedals.com and they are as amazing sounding as they look. I've also commissioned a few other pieces through them for custom bends of pieces and I all have turned out to be some of the best noise machines in my arsenal, and I've bought from most the major benders out there.
