I like mine. Excite Truck and Zelda are especially awesome, although I wish I could just use a gamecube controller on zelda, the swinging thing is pretty lame in that game.
Rayman Raving Rabbids is pretty lame, they have all these mini games where you have to swing like a crazy person. I haven't found any other games that were good. Games like excite truck have it right because they use the controller in a way that makes sense, zelda, too, except for the sword swinging (it's great for aiming bow & arrow, hookshot, etc.). Rabbids is like they sat in a room thinking of lame ways to move the controller.
The cost is really low, and there are a bunch of games I am looking forward to, like mario, the next zelda, metroid, and hopefully some GOOD first person shooters (no, red steel doesn't count as one, because it's lame).
