My oldest is dying for a kinect. Ya know that thing that hooks to the Xbox 360 and requires no controllers only your body. This thing is great. I know that they keep selling out in a few places but you can get them at your local Wal-mart or K-mart or Target any place like that.
You can check out the kinect games before you buy them from http://KinectGamesForXbox360.net See a lot of the kinect games and watch a preview for them before you buy them all in one place.
