How much did the logitech run you?
I still say the Kiky-X Series is the way to go. You can get PS2 driving wheels, light guns, dance pads, etc. a lot easier and sometimes a lot cheaper than PC versions.
acemcmac: What was the name of that adaptor that does N64 adaptors as well?
One last little thing: anybody know if a GameCube -> Dreamcast adaptor exists? Gamecube -> PS2 would work, even though there aren't enough buttons. I have a PS2 -> Dreamcast converter.
Or a PS2 controller shaped exactly like a GameCube controller. I found plenty like it, but they're always off in one way or another.
