I don't even bother looking at used guns anymore, usually people want more than they are worth. However, I've been offered to buy used guns for a pretty good price by people needing quick money. A few months ago a guy offered me an S&W 629 .44 mag with a scope (not sure the brand of scope) for 600$. That is a freaking steal but I didn't have the money at the time, and it wasn't really on my list of guns I wanted anyway. I know a guy who is always falling into great deals. The secret is knowing a lot of old rural folk.
