Actually reading this thread has got me thinking.
I hate LOWBALLERS. If I bring a firearm to a show to sell, I want to get a decent price for it. I'm not looking to make a killing, maybe a little profit from what I bought it at would be nice but I'm also willing to take a loss if it is acceptable depending on the condition of the gun and the customization involved.
But come on....some of the lowballers are just plain insulting. Example: I once brought my Remington PSS (rare one with a factory fluted 24 inch barrel and not the regular 20 or 26 they come in now). This PSS had a Harris bipod, $300 for the premium mount and rings (didn't bring the scope) and a $300 10 round detachable magazine setup, not to mention the crap load of money spent on trigger jobs, and extra customization.
Darn gun had been only fired less than 300 rounds in the last 10 years and was in almost NIB condition. Some guy asks to see the gun and after fondling it for a while offers me $250 for it. Jeez dude, I really don't mind negotiating but not with such a low starting price. This thing will consistantly shoot 5 shots in one ragged hole @ a 100 yards I told him. "Well, these things sell for $450 new all the time so $250 is the best I'll do". I told him politely no thank you" but in my head said to myself "if I wanted to get screwed, I'd go home to my wife first".
I actually took it a little personally as my guns are like my babies. I've spent many hours holding them in my arms and polishing them and cleaning them so they sparkle. But enough of my sex life.
Either way most people think that if you bring a gun to a show to sell, that it means automatically they can take 50 to 70 percent off the value of the gun. But then again, lots of dealers of used guns put 50 to 700 percent markup on the guns on their tables. When it comes down to it, an uninformed buyer/seller will always get screwed in the end. Kinda a shame.
