One of the best things about gun shows is that licensed dealers from the surrounding area all usually go there, it lets you see who has the best prices and if you find a good price, you can go to someone else's booth and tell them that the other guy has it for 500, then ask if they can match it or do better. It breeds a good environment for the consumer.
