As much as I love vintage Slingerland drums, I think that this guy is a dreamer by asking $599 for the bass and tom. No serious or even semi-informed Slingy lover would pay more than half that amount for those two pieces. I would offer $150--$200 at most. I feel somewhat exploited by an opportunist who asked advice, and then decided that he knew better than the more knowledgeable people offering advice. From now on, I will qualify the people asking advice to determine for what reasons they ask for the advice. If they are flippers, I will give my pricing advice based solely on what I would pay for the items. Just like on Antiques Road Show there is an insurance value and a real world selling price value. And, just like on Pawn Stars, there is perceived value to an end user and a selling price that are not the same.
