Same deal here. I've come close, but never jumped. Most of my collection is pre '80 S&W revolvers, even though I don't consider myself locked into one style or brand. I'd love to get a nice Dan Wesson 1911, and a Colt Mustang someday, but every time I start to consider it, another cool S&W revo comes along.
Since my budget for the gun hobby is not endless, I tend to consider cost effectiveness, bang for the buck, resale value, along with the usual gun specifics as mechanics, dependability, etc. When I briefly considered one of the new plastic pieces, I kept wondering in the back of my mind what old Smith M&P or Airweight I could be getting for that $$. Needless to say, I'm still autoless for now, and it doesn't bother me. I'll pick up a nice auto someday when a good deal comes around, but my J frame will still be riding in my pocket, and an N frame will be in the headboard. I'm pretty sure that will not change.
