I think the last few copies which were MIB on ebay sold for more than $1,700? With that said, this may have actually been a "deal."
I already own the game w/ manual (kinda meh condition), but that's good enough for me. However, if I A.) didn't own the game, B.) if it were tax return or x-mas bonus time, and C.) could've talked him down $200... I would've maybe considered.
