Hey, thats funny. I just hacked the hell out of one of those to put buttons into my console. I just soldered pushbuttons from radioshack mounted into my custom console onto the PCB for the thing. The software I'm writing accepts input from it, it's pretty cool.
Anyways, I like it because its all playstation style. I will probably by it if no one shows interest, or if I find out they are hard to find (haven't looked yet)
