I LOVE GUN SHOWS!!!!
I've been going to gun shows for about 20 years now. I almost always buy something. Last time, I bought this Chinese knock-off Eotech red dot sight. The thing looks great and works pretty well too - cost me $100! Surprised that Eotech hasn't put the hammer down on these guys. Oh well, not my problem - I think Eotech's stuff is priced way too high for what it is, so I've got no problem buying the Chicom knockoff.
Lets see, I picked up a Detonics Pocket 9 several gun shows ago. Ehhhh, not a bargain, but a tad better than I could find on Gunbroker + shipping. I just wanted one, and there it was - a really nice example.
The time before that I got an Israeli made grip bipod for my AC556. Now, this thing is a nicely made piece of equipment - legs made out of heavy extruded aluminum - perfect forward grip and I like the bipod feature - think I paid something like $40 for it.
Then, there are always some interesting knives - don't usually buy those, though.
I always end up learning something new at a gun show - that and the entertainment value alone is worth the $8.00. Considering I'd have to spend $80+ to watch a basketball game:barf:, I can't figure out what gun folks have to complain about?
