Or, since he's in a huge metropolitan area, ask if you can come over and look at it!

Very, very true! I have been insisting on local pickup for large purchases lately, and the response from the seller when asked about this is VERY TELLING! It is funny when you find someone that is a bit dodgy, their response and excuses as to why they cannot meet with you are quite hilareous. My new policy for high-end purchases: "No see, no buy". I lose out on some good deals that way, but I am never to be burned again! I will drive between 4 and 5 hours to get a good piece.
