Some valid points on both sides. I haven't sold a call on eBay....ever! If I did I would put a reserve on it and hold to it. The problem I see w/ using eBay for pricing guide, is that many sellers don't provide the correct information w/ the call or the photos are so bad, you can't get a good idea of what the call looks like or its' condition. This can make for a bad auction, all around, which forces the average price down. Also, many calls show up in the wrong listing area causing the bidding to be sparse.
