I've recently contemplated buying eBay lots of certain systems I wanted to expand on. Mainly Gamecube and original Xbox. I've encountered a bit of a problem though. They're all stupidly priced. Seems hardly any of them worth anything is being run auction style and the others are a set price with "best offer", which gives me the feeling, that the seller is way too proud of their stuff.

Opinions? Should I just stick with garage sales and thrift stores? Usually, I feel if I can't get them for $4 a game or less, for a common game, I just pass. I felt that if I was buying a lot of games I wouldn't want to pay more than $2 a game. Am I just being unrealistic?
