$140 is about right for that game (is paying that much for any game is "right"). with a lot of searching in japan, you could probably get it for $120 (during the dollar's better days, that is). i have also seen it there for $180+. the problem with 1941 is that it's just hard-to-find. it rarely pops up in japanese stores and often sells quickly. i haven't checked to see what this is going for on ebay anymore but i'd say this:
try getting the guy to bring the price down a bit. ask for $105 but settle for $120 because you are getting to see the product for all its mintiness before you pay and you will never get that with ebay. on ebay, if you pay $110 and factor in the shipping costs and the slight risk factor, it could wind up costing you the same if not more. rest assured though, at 140, he's not trying to rip you off. good luck!
