Gun shows are a circus where you pay a premium for the chance to spend your money. There is the occasional value or thing of interest but as far as I am concerned Internet shopping has for the most part made them obsolete. That does not mean they arnt occasionally fun and dont occasionally get my money.
No matter where you shop you can find deals if you do your homework and have the experience to know what and when to buy
The net is a pain in the butt for deals unless the seller or buyer is close. Buy a gun off gun broker and you have shipping and dealer fees plus you really never know the true condition of the gun until it's in your hands. Know a guy who put up big money to buy a Thompson full auto that returned it because it turned out to not be what was advertised.
Most of the guys selling can't take a picture and certianly have no idea how to sell a gun. They don't even clean them before they take a picture. They don't understand when they offer all the extra parts it creates suspicions as to the quality of the gun. Guy offers a gun with another gas system with it yet in the picture if you look close you can see carbon build up from a leaking gas system. So let's see, extra gas system and leaking one on the gun but just like new in the add.
The net is harder to find the good deal and there are too many guys wanting to buy that you compete with thus driving the price up. I would rather deal with a vendor or a dealer face to face that I can size up and work out a deal.
