I will put in a plug for Lock, Stock & Barrel, an outfit that sells on GB. Recently needed to make room, and so picked out 13 that I thought I could part with. They tour the country and actually show up at your house, inventory the guns, give you a receipt, and haul them off. Their commission is 25%. I've seen other GB sellers at 17%, and my LGS charges 20%. But I think these guys earned their premium. If you read their postings, they are very detailed, well photographed, and very frank. From a buying perspective, they inspire confidence. I did very well on my sale, and deposited a nice check yesterday.
