I was in line too. That is the most people I've seen at a gun show here.
Bargains, there was a LLama 45 for $250.00, I found Mil AR-15 30 round in bags for $10.00. The guy in the front left corner had AR-15 40 rounds for $15.00. There was a guy selling AK-47 for $400.00. The last one I ordered from my FFL buddy cost me that after the shipping, sales tax and his fee.
I guess it all depends on what you are looking for there. The best gun values are the folks walking aroung. I stood in line with a guy who had an M1 Grand he would have sold to me for $550.00. I should have bought it on the spot then sold it inside for $800.00 but I did not have that much cash on me.
New or used I did not see an AR-15 of any type for less than $800.00. Saw two M1 carbines for $350.00 a new rebuild and a used in perfect shape. Found some true CETME mags, not HK or G3.
Most of the rest of the stuff, we can order it new through our FFL friends for less than what they were trying to sell them for used, except for the real old stuff that is not made anymore.
As it says in the book, seek and ye shall find. If they have stuff they do not want to haul back home, maybe today will be bettter for trying to deal with them.
