I bought one around a month ago for $500. I had been waiting for one in my price range for a year and a half or so. They appear regularly on Gunbroker auctions. The problem is that most of the people selling them there, particularly dealers, think they are selling the crown jewels. Minimum bids are so high that no one bids. One dealer had a couple 2 inchers listed for, I believe, over a year. His minimum bid, for months, was $800, until he got charitable and lowered it to $725. As of the time when I bought mine recently he still had no bids. They were nice guns, but not that nice. Neither came with box & etc. as I recall.
Back to the OP: I use mine to practice trigger control for my .357 carry piece. It's going to take a good bit of practice; with those tiny things the slightest twitch, jerk, pressure, etc. will throw you off -considerably.
Keep the chambers clean, and extraction should be OK. When I got mine I used small pieces of lead-away cloth in a section of cleaning rod and a loop tip, and ran it on an electric drill. Then took the gun out on the range and ran about 160 rounds through it with no extraction problems whatsoever.
Best wishes in locating a good 34.
