As mentioned, he's very well known around here and we all know to stay far away from him. Like I said, sorry you got bit by him, but life moves on and X > 2 so you're set.
I didn't know about him and got shafted through ebay. I bought a few MVS carts, and it said something in the description along the lines of "condition may vary on game than what is shown in the picture." So, since it was a few low dollar ones I wasn't too worried about, I tried my luck. They showed up, and all 3 carts were not only scratched to hell, but he had removed the original labels and put on poorly printed bright red and white labels on the carts. Nowhere in the description did it say the labels were removed.
I guess it's my own fault for not asking first and doing my research, but I was, and still am, a little salty about the whole situation.
