Welcome to the forum! I have two 581's, both with 4" barrels. One in blue and one in nickel. Both are boxed and in very nice condition. I purchased both about 5 years ago, in the $300 range. I considered that a very good price at that time and snatched both up. Today the market would be closer to $400-450 for a nice one. I don't see many 581's in my travels anymore. I don't see many 586's either. These are great guns and you should seriously consider a purchase if the condition and price are right. With the prices of new Smith's going up and up, collectors and shooters are snatching up the older revolvers. Good luck!
