yep yep, biggest thing i look at, as goinloco1 said, is the post count + bst rating. the higher the post count, the more they've been around on the board, the more likely people know of them and maybe some people on here know them personally or have done business with them. the buy-sell-trade rating, good to know that others may have already had good transactions with the user. oh, and ask questions. it never hurts.
didn't know bout the escrow part though...
