Great - thanks for the information. I figured the value was low, but didn't know how low. I read somewhere that at one point the company was shipping around 100,000 a day... or maybe it was 10,000. So I knew they were numerous.
I plan on keeping it for now, cleaning and maintaining it, then seeing if it still fires. It cycles cleanly, but the main spring is bent, and I don't know if there is anywhere to get parts. The grips obviously need work, but I have not seen any online either.
