At five bills, it would be on the high side of what I would like to pay. (but then, most used guns sell for more than I think they are worth) Having said that. If it was a gun I was looking for, it would be mine. Most any Smith is bringing that kind of money, if it is in decent shape. I can't remember when I last saw a 13(of any dash)for sale, in this part of the country. And have never seen one in the local shops.
Used S&Ws have taken on the same aura as Winchesters had/have. They are asking premium prices even for badly used and abused samples, just because they can. To people born before, lets say, 1960, nice S&Ws or Colt revolvers are a thing of beauty. An example of the highest mark of craftsmanship and manufacturing expertise. (other guns fall into this same category, fine shotguns, good rifles(even the lower priced brands) While most but not all folks, born later, don't even understand the concept of "high quality" and can't understand why anyone would want "that old piece of **** gun" (insert your preference, Colt, Smith, Browning, whatever), when you can buy the latest and greatest plastic, alloy and spray painted "wonder gun"
OK, I went off in a rant, the last half of this post and far off topic. Sorry about that.
Back to topic: If you want the 13, for that price, you should buy it. If you don't, someone else will and probably soon.
