N64s and their games are going for peanuts around here. I know a electronic junk store that has a dozen of them piled up for $10 each with controllers and the games (mostly crap ones I'll admit) are $5 each. I'm glad I hung on to my N64 and even though I don't use it much, I don't think I'll ever sell it.
@TCD: You know you can get an adaptor to use a real N64 controller on a PC right? Having a proper controller makes emulating more bearable.
