I wouldn't worry too much about the asking price. What matters in a sale is what it actually goes for. MKs are floating ar $350-$650 working so I doubt he will get the $800+. What gets me about people like this is they bitch when you put a $300 price tag on something that you know they are going turn around and stick $800 for sale sign on. This is why I rag ops about their prices so much.... games are only worth a lot of money when they sell them, if its yours its only worth $100.
