I'd really like to get a Model 10, mostly just because, and you can still find them for reasonable at least not outrageous prices.
I'm embarrassed to say what I paid for my most recent Model 10. And it probably *will* be my last one. The prices for nice examples really started climbing a few years ago.
I'll still scoop a nice one if I ever sneak up on one at a good price. But it's gotten very unusual to sneak up on a nice older S&W revolver.
