I still enjoy going to gun shows, but they sure seemed better when I was a kid. It's been a very long time since I bought a gun at a show. I am one of the ones who just wanders around looking at "what's out there", occasionally stopping to paw through a box of miscellaneous odds and ends or old reloading supplies.
I walk right past the tables of new guns, the dealers with the latest, greatest HK or Glock, ARs and AKs (nothing wrong with that stuff, It just doesn't excite me any more). The last show I went to I bought some brass ($1 a box, 30-06 and .300 Win Mag), some assorted old bullets for reloading, a rusty but very useable Rock Chuck press for $30, and a couple hundred rounds of Yugoslavian 7.62 for $15/100. I don't shoot much of that caliber but I figured these days that's a good price and I would pass it on to a friend. Then there's always one or two dealers at the shows here that have ammo at internet prices without the shipping.
There's also the same old dealers with incredibly overpriced junk I've learned to simply ignore, one guy in particular who always has a scowl on his face. He never has price tags on his stuff and I've always regretted it any time I've ever asked about something. I have always wondered how in the world he makes any money at all when he's wanting twice as much as the guy two tables away for the same thing. I guess he just lives off the occasional sucker.
I guess you just take the good with the bad. Go for what you like and ignore the rest.
