How much should I spend on a Wii bundle with the Fit thingie? And is there some place to buy it where it's cheaper? And with the Fit thing, do I have to buy the Fit game or if I get any package with the balance board thing, will that have the game? Basically, I haven't really ever bought a video game system and I don't know shit about 'em, but my mom wants this and I wanna get it for her. But I'd like to shop smart. Thanks much for any guidance!
