WTB DC to PC converter

The ones I see on eBay (Trio Linker Plus II) apparently suck, so I was wondering if anyone had a used PC USB converter they no longer need that supports DC pads/sticks.

Edit: The Mayflash Super Joybox 3 in 1 looks like the best one, but is out of stock everywhere. I would really like to get one of these!

Found one.
