You say you've been to this show for 'many years.' When was the last time you attended? It has been under at least 3 different 'managers' that I'm aware of.
I do some work with the show. The current management held their first show last February. It was the first show there since 2005, and was very crowded, because it was in one of the smaller buildings. We really didn't know what to expect.
The show is now in the largest building, Fairhaven Hall. I attend a lot of gun shows, I've been to auctions, and I've read gun ads in the paper. Every vendor sets his or her own price, but I don't think these are overpriced by any means, the used ones or the new ones. Where, might I ask, do you find better prices?
