I found this lot on CL. I offered the guy $400 and he countered at $500. I accepted the $500. I was supposed to pick up tonight, but he backed out saying someone offered him $700
I had a find like that once while I was in Las Vegas. Sorry it didn't work out for you. I think my find was something like $300 and included 2 Marvel Vs. Capcom 2's back when the game sold for $80ish and it also had tons of other systems and games. Still probably the best find I've ever had.
