Even the Wanenmacher show? I've gone there looking for specific firearms, and come out with something different. This time, I really wanted a postage stamp IHC Garand, and left with a M1A with almost all USGI metal parts (except the receiver, of course) made by the original Springfield Armory - something you just don't see these days.
The size of that show, IMHO, increases the chances of finding something that tickles one's fancy, so the entry fee isn't as much of an issue as it is at the smaller shows.
If you are a collector of rare and or unique firearms, Wannemacher is the place to be. If you want a Glock, it's hard to swallow the fee when local stores are cheaper anyway. I only go to the shows to look for something rare.
