I just bought a wired one from Hong Kong on ebay. It was 15ish. Ill let you know how that works out...
I see some generic PS3 controllers on eBay that are wired, but it looks like they don't support SIXAXIS functionality (plus no "PS" button). Probably why they're cheaper. Not sure if that's what you bought (didn't notice any from HK).
Yea I saw those....not sure if the support the Six Axis. Im pretty sure they dont support PS2 or PS games.
