About 18 months back I got a -2 (Model of 1988) for around $650. Thought I had a heck of a deal until I opened the box and found it had severe push-off and one shoulder of one chamber was buffed bright. Felt like I got taken until I put a stock main-spring and 14 or 15 pound rebound spring in it. Not only was the push-off gone but it ended up with a very controllable DA trigger pull. That shiny spot is still a little off putting (you can see it in the second picture - lower side of the cylinder) but over-all it a great shooting gun.
Be advised, the -2s have the floating hand, which is supposed to be a bad thing. I'm sure it is (who would lie about something like that?) but the hand in my gun hasn't caused a single problem yet. I will probably get around to changing it as soon as it does. (smile)
