And then there's this S&W, Stroh-tuned oddball
http://www.gunbroker.com/Auction/ViewItem.aspx?Item=492046175
Factory looking 686 with 4" half-lugged slender barrel, pre-Mountain Gun, factory marked. Owned and tuned by Jim Stroh.
And affordable.
Weird, and tempting.
The same seller has a nice .44 Special 3rd Gen SAA too.
Quite reasonable for a starting price.
