+1 on collecting modern revolvers, at least now, except for the really high end jobs like the pre 1982 Smith & Wesson Model 27 and its predecessors, the Colt Python, and a handful of very low production models. The real dollar value of almost all modern revolvers hasn't gone up that much, even in excellent condition. That includes the high end ones I mentioned, except the Python and S&W pre Model 27 .357 Magnums.
To most people a good modern revolver, even a nice Colt Detective Special or S&W Model 15 are still just nice useful used guns for carry, nightstand or hunting use.
I also agree that the price on the revolver in the O.P. is very fair.
