Wii Classic Controller Available in U.S.by, aquatsr
Released right on time judging from
's post back in January, Amazon has this controller for $19.99.
The controller is available in both black and white colors and provides essentially the same functionality as the Classic controller but with a better grip. The controller plugs into the Wii remote in the same place as the Wii Motionplus and the Wii nunchuck.
Unfortunately the controller isn't compatible with Gamecube games, but it offers a better solution than the older Classic controller for playing Wii games as well as games downloaded from the Wii Shop Channel.
