So much of it depends on you. If your buying and $3k seems reasonable then who can argue with that, shooting's a hobby and worrying about a couple of hundred bucks isn't productive nor will it break the bank. The gun is largely discounted from new so you can shoot it for a few years and probably get close to what you paid for it. I'd be less enthusiastic about it if it doesn't have optima barrels though, but that's just me.
If your selling, I'd probably ask $2900 obo and see what happens.
