i've never been to a frag swap, and i'm not really a club kinda guy, but i can definately see how this could be really cool or really lame... I've been to enough ham-fests and swap meets to know that some people show up with some junk that they are really too proud of $$ wise, and then there are thoes rare jewels tucked away in a corner, just waiting to be discovered.
same is true for the saxet gun shows, if you know what your looking at, and can talk inteligently with the seller, you can normally talk them down on the price, but if you dont know, well, they might as well make a little extra profit then, huh?!
then there are thoes sellers that they dont know what they have, so you either can talk them into a hell of a deal cause they dont know better, or they arent willing to work with you at all cause they dont know how to...
