I also have very little luck at FL gun shows. Most of the vendors are absolute jerks. I am tempted to do my own gun show:
'Florida's Finest Gun Show'
It'd be me, a laptop pc, modem connection and a $3 cover charge. I feel I could beat nearly every price by shopping on the 'net.
There's only one FL vendor I have true respect for, it's the guy who sells reloading supplies (can't remember his business name??) and reloaded ammunition. He has GOOD PRICES, well laid out tables, well packaged reloaded ammo AND MOST OF ALL IS INFORMATIVE & POLITE!!
