To me, those prices seem fairly reasonable for what they are individually: factory refinished, long-barreled, kind of uncommon, but modern editions. It sounds like somebody went to a fair amount of trouble and expense to get exactly what they wanted: a set of shiny, long tubed k-frames. It would be seem to be sort of a shame to break up such a set. Honesty, they all sort of appeal to me, but seeing as how S&W never offered a nickel M14; if I was choosing only one, that would be the one. Very unusual and no chance of it ever being mis-advertised as something that it's not. Although there would be some attraction to being able to say that you've got a genuine, factory nickel K22 (....hmmm, I like K22's).
I don't know about the short-term collect-ability of the set of guns that you're looking at, but for some reason I have a feeling that you may kick yourself later on if you pass on them. Mostly because they are 1.) nice guns in their own right offered at a decent price, and 2.) because you just don't see these editions in nickel very often. I don't think that the fact that they were re-finished by S&W (assuming that can be documented) detracts from them that much. However, if offered as a group, you may get an even better-to-great deal. If you can swing the complete set, that's what I'd do. Good luck with your decision, and if you get one (or the whole set), please post some photos. I'll bet that there would be a lot of interest in them here. -S2
