Cross-referencing this thread to the various rants about dealers being, well shall we say, high-minded or insensitive, I can't help but wonder if what we have here is the amateur seller's equivalent. Sure you have to answer obvious questions, if there was a qualifying test for purchasers many a sale would not see the light of day. Insofar as shipping to Canada, many times purchasing model railroad items on ebay I had to inquire about how serious a seller was in indicating shipping to the US only. Many a time the seller replied that, on second thought, it wasn't a problem. Maybe model railroaders are naïve, who knows. Mr. Lugnut, are you more averse to changing your mind than your audio equipment? Sure it's easier to not sell any piece of equipment declared surplus in one's system, but once you enter the marketplace you should expect to sweat a little sometime. How about the other fellow who posts ads for good equipment at ridiculously low prices and feels that he has no obligation to sell at that price if someone accepts his offer? Would we accept a dealer doing this? If you start in the buying and selling game, you should expect that every prospect will not turn out to be a buyer and that all prospects may not be as savvy as you. You should adopt an attitude similar to that you would want displayed by the type of dealer you would patronize. If all else fails, you could always sell to a dealer and let him/her field unwanted inquiries and pay the price to avoid dealing with the riffraff.
