A lot of the models that I'm interested in are no longer made, which makes buying used a necessity. I might add that a lot of the models that are still made today aren't made nearly as well, IMO, as they were back in the day -- and you can go back as far as you like. Let's compare the S&W-made PPK, for instance, to the ones made by the Germans, or the French, or even the ones made by Interarms/Ranger a couple of decades ago. Nothing wrong with the old stuff, I say.
