I agree with you Bigmoney and it's admirable that you take the approach you do when dealing with buyers. I'd want the same treatment if I was buying from someone, and I gave the same respect and positive encouragement to the guy who bought my pool table on eBay. It's not unreasonable to expect a certain amount of courtesy.

Only problem is, the world is full of jerks and arrogant idiots, so this probably isn't the last time you'll come across someone like this. In time you'll realize that you either accept the risk of going through these types of situations, or use a more old-fashioned way of doing business in the used gear market.
