Keep in mind that Amazon list prices mean next-to-nothing. I could list this bottle of Poland Spring that's infront me for a grand if I wanted to--that doesn't mean a single person is actually going to buy it at that price. If you're going to check prices online, at least use ebay's
completed listings search and look for the green listings (ones that actually sold successfully) and don't ignore factoring in the prices of red listings either (ones that
didn't sell--sometimes cheaper prices but still didn't get bids).
So far I see comparable listings that sold for... $125, $80, $145 ("never used"), $186(!)... actually much better than I assumed. Of course, most of those high listings were in new or "excellent"/"great" condition.
I did see a drumset by-itself that sold for $90 plus shipping; of course there's always a chance that the end-buyer backed-out after the auction ended (which although rare in-general, and has happened to me in the past, it happens when people bid without really reading first) and you really don't know to see the listing.
So at any rate, I hope there's a few things to think about when considering setting prices for "friends."
