I havent bought or sold any guns in a long time. I do have considerable experiance years ago haveing tables at gun shows etc, and I would guess about 300 guns have passed through my hands buying and selling. Here is the biggest mistake that I made many times. That is passing up fine guns for the sake of maybe the owner not comeing down another 20 bucks or so! Nowdays I throw twice that much away every day doing lunch or whatever!
