I have some extra new, boxed first party sega saturn pads. They are not the huge saturn pads, they are the jap style, i.e. like the usb/ps2 saturn pad. $20 shipped for a pad.
edit: Added a pic. On the right is the one I use on my innovation dc adapter. The rest are boxed up like the one on the left.
Any questions or comments, post here or pm me. Thanks!
