I just thought I would bring this up, as this really bothers me.  IMHO, the best USB gamepad ever made for emulators is the Sega Saturn USB gamepad done by Sega's ST Labs circa 2004.  I bought one years ago, but it has worn out, and they now sell for $80+ on ebay!  There are some junky Play Sega branded controllers you can take board out of and put in a vintage Saturn controller, but you're either going to pay crazy money or break out a soldering iron to get one of these now.

So here's my question:  Why aren't Sega selling these?!  The ebay/Amazon prices show the demand is there, why not produce them?  Maybe Sega could try a Kickstarter, even?
