If the pre-17 was in good shape, that was a good price and I would have jumped on it. Now as far as the 17-2 from what I can tell from the pictures it's probably in at least very good condition, if it's mechanically sound, and the book lists it at $625. One, it's really hard to tell from the pictures; two, we can't say without at least a description of it's mechanical shape and what are they going for in your area? Let me give you an idea of how prices may go. Recently I went into a LGS and he had a beautiful model 43 in excellent condition with no extras such as a box. The price tag read $950, I offered $700 thinking it was a good place to begin bargaining for it, no dice, no coming down. Now, the book lists this revolver in excellent condition at $750 and as new in the box for $900. I wanted it and would have gone to $800 however, it's not in my collection and won't be for the price being asked. The book I keep mentioning is the newest edition of the Standard Catalog of Smith and Wesson, 4th ed. All we can give is a rough ball park figure when someone asks for a value. Again, I really thing you should have purchased the pre-17, that price with all things being good was fair. Newer doesn't always mean better!
