That sounds like a good price to me if the gun is in good condition. I paid $225 for mine which I believe was unfired within the last couple years, but I consider that a steal. I didn't hesitate for a second and would buy a dozen more at that price.
One more note: I believe I own 10 or 11 S&W revolvers. They are all sweet. Nice smooth actions, beautiful trigger pulls, accurate etc. But my Model 28 is in a whole different league. It is the epitome of revolvers. I was telling a buddy of mine the other day that I should loan it to the Performance Center to use as an example of what a custom revolver should feel like, but as far as I know, it is bone stock. In a phrase, it is a work of art. Just opening and closing the cylinder brings a smile to my face. I sent my Model 29 to Jack Weigand and it came back a masterpiece. But even with the custom work, I would still say my stock Model 28 is the better revolver.
