We had announced the release of Talismoon's tiltBoard here and the available preorder, here. Now, we were informed that there will be premodified Xbox360 controllers with the tiltBoard installed into the controller for those who cant or dont know how to solder.
You can purchase the black or white premodified Xbox360 wireless controllers from TotalConsole. They have been tested before being sent out. Both controllers come with a 90 day warranty against defects. Unfortunately, the price is expensive. It will cost you $99.99. Once things are more streamlined, price of controller will go down. When? No one really knows.
