I liked the group. Looks like a cool deal; I've done a controller paint job before (on an N64 controller)...I never finished it though; I lost one of the C buttons (Why God; TELL ME WHY!").I have about six N64 controllers though; so I'm thinking of just taking one of the C buttons from one of them until I can find a busted N64 controller to scavenge a loose button from.
On another note; is your friend only going to make some color changes & LED implants? I saw the controller with the Captain America emblem on its two sides, but nothing else with any decals or designs in particular. Controllers with some clear, well-placed designs would probably sell a lot more than ones without said designs; it shouldn't be too difficult either. I bet it'd be fun for your friend too.
