The 357's should be back soon, in SS only though. There are more than enough older ones around to keep me happy. I have a blue Model 15 4" and a 6" 715 I got in almost mint condition for less than $300, with 3 grips, two pistol rugs, a few spare parts, and in the original box.
A friend of mine doesn't like them at all for some reason, but he paid $500 for an S&W 686 that needed some work before it could be shot (broken spring). He had to take it somewhere to get it fixed. I can take one of my DW's down to a box of parts and put it together, without any tools other than the wrench that came with it, within a few minutes. I think the problems some of them had later on made people think "They're all junk". I put thousands of rounds through the first model 15 I had, without a single problem. It recently turned up in an action online. A pawn shop had it for sale. I called them and asked, "Is the Model 15 you have for sale, serial number XXXXXXX?" The guy laughed and said "Yeah!" I lost the auction by a buck. I recognized it by the grip I had made for it in 1981, and the huge gouge in the frame right above the grip on the right side caused by a whacking it into the corner of the steel desk inside the security office where I worked. I really wanted it back, but it all worked out ok as I got the SS 715 a week later.
Another friend of mine, not very knowlegable about guns thinks the changeable barrel idea is crazy. It's worked fine for what, almost 40 years, and he thinks it's crazy? He's been listening to his one bud too much, the one where any auto but a 1911 is "junk", and any revolver that doesn't say "Python" on it isn't fit to shoot.
