I second the notion above, and I highly, highly recommend going this route if you decide to go for complete games. I've been doing it this way for years and I can tell you that it's much cheaper to wait out a mint copy of a game than to buy every crappy copy you come across over and over again until all components are mint.

My mantra, as worded by SamSpade on 06/12/12:
I don't resell to fund my collection, I don't treat this hobby like a second job, I don't care if my collection is worth ten bucks or ten thousand because I never plan on selling it. Seriously, what does the value have to do with anything if you never plan on selling? Speculation doesn't mean jack shit to me at this point, I just want to play my nes games...
