for me, ebay is the best guide to almost anything you would ever hope to put a value on, as well as the worst place to sell at. its also why i stopped selling anything on ebay years ago, i got tired of trying to sell my game new in box for less than the next guy selling the same thing.
for me, for selling old stuff you are much better off using a local buy/sell paper, cause most of the time theirs not another guy selling one.
