Don't know about the price, good or bad, but the S&W Model 27 is an excellent revolver.
The model 27, and the 28, are "N" frame S&W revolvers. These were the early models
made for the 357magnum. The 27 is the higher grade version with better blueing, target grips, hammer, red ramp front sight, and I think a white outline rear also.
The model 28 was the service grade version.
