Saturn Kiki Joypad

I bought the same Saturn pads at , it's not very good, but it'll do the job I guess. I can't describe how it feels that well, but the l+r triggers don't really have a spring after you press it, the buttons are cheap and not that smooth, the d-pad also feels cheap, the edges of the d-pad are sharper, so you'll hurt your thumbs if you play with these for a long time. If you're really desperate for controllers, go ahead and get these.
If you're looking for official pads try ebay. There are lots of auctions for official pads (often in boxes and in new condition too) for very little. I managed to get myself 2 brand new 3d controllers (the nights controller) for $4 each.
