I picked up the 'Innovation' controller adaptor last night; the one that lets you use PSX/PS2 controllers on your XBox. It was $25 at Funco. Here are some quick thoughts. It doesn't work with original PSX steering wheels (neGcon compatibility standard). I doubted it, but had to try it for myself. It works with a PS2 Dual Shock controller, and the lower shoulder buttons map to the triggers on the XBox controllers. The pressure sensitive (256-position pseudo analog) functionality does work, giving you analog control. However, it seemed a little twitchy to me (which could just be me). The functionality of the analog sticks and the other buttons was fine, and the rumble feature seems to work pretty well. I may take it back, I was basically gambling on the steering wheel functionality. But for standard pads, there will definitely be some fans of this adaptor.
