that's a pretty solid deal. However you could check out all your local Sears and see if they have the Metroid Prime bundle in stock, it's 50 bucks on clearance brand new...
For the most part a new one is 99 bucks new and about 60 used.
i just checked the sears and while they had the bundle, it still rang up at $100. i would have got it for $50, and a few games for the wife. too bad though.
