Suggestion Request

I am considering getting my 3 little space monkeys a nintendo gamecube for Christmas (I can almost hear the offended cringe at the phrase). I like the fact that some come with a couple of games, ie StarWard clone wars and tetris worlds. They already have two gameboy advance's that I hear hope make decent controllers for the 'cube. Anybody got any experience with such a setup?

SpaceMonkey AWAAAAAAY!!!!
