Normally, I only look at the guns on Gunbroker that draw bids. I have bought a couple of guns that were listed otherwise and I think I got them at a bargain simply because serious buyers ignore the prepriced or reserve priced guns.

If I sell on GB, I start a .01 with no reserve and almost always feel the gun brought what it was worth. I always put a counter on the ad and rarely list a gun that doesn't get 1,000 looks. If a gun gets 1,000 looks and sells for less that I thought it should, it tells me I thought it waa worth more than it really was.
