The one on the left was my first one I bought and the one that fueled my interest in S&W revos, I traded an AR complete lower, ammo and cash for it...about $700 worth of stuff. Local trade
The middle one I had to have and traded a guy a new Glock 26 and a ton of mags and ammo for....about $600 worth of stuff. Local trade
The one on the right I bought out right for $550 and was happy to get it locally at that price.
They are worth what someone will buy them for. I have my limits, but I am not sure what that is as of yet. Do I feel I spent or traded more than I should, absolutley, but I wanted them and now I have them. I had a friend tell me, "you never pay too much for them, you just pay it a little bit sooner than some".
