Best place to buy USB controllers? (NES, Genesis)

[Organ Donor]

I've been looking around online for NES and Sega Genesis USB controllers and was just curious to know if any fellow CAG's could point me in the right direction as to where the best deals/quality ones are. I have found a few on Amazon, but most of them have mixed reviews. Making one on my own doesn't seem worth the time and effort... I don't have a soldering iron anyway.

Think geek has an NES controller for 29.99. Price is high, but coming from them it most likely pretty good quality.

I use a Street Fighter Fight Pad. It works just fine.

Retrozone seems like they're out of the USB stuff. I found them a lot cheaper at DasCheap. Same ones made by Retro-Bit.
