re: "I'm going to the Dulles Expo Gun Show tomorrow."
I might just see you there, CTJ. The wife enjoys the show.
I've only bought a couple of guns at gun shows. My first AR-15, and my wife's Ladysmith. Maybe one more.
The thing is, why buy a new gun at a show, pay the tax, AND let the state know you have it by registering, when quality used guns can be obtained for half price in face-to-face transactions? The majority of my firearms were either bought second hand, or obtained from local stores where my wife has connections. She sometimes gets offers that are just too good to pass up. (such as three single-shot shotguns for $150.)
Show prices can't compete. At this point, I'd only buy from them if I was looking for something special.
