www.guwholesale.com has the 2" SS new for $275. www.gunbroker has new and used for around $250 to $300. Do some shopping around on the web and you'll find good deals. As for used around the neighborhood here, Ive yet to see one. New at the local shop they're around $320.
I took the wife out shopping for a .357 and the two models she liked were the Taurus 617 and 605. She picked the 605 cause it fit her hand better. For some reason the handle seems to be a little different. Just enough to make her want the 605 instead.
I got my 617 w/ 2in ported barrel at a local shop for $300, used but in flawless condition. You can probably find it for a little less, but I liked it enough to do an impulse buy when I found it. Glad I got it, it's a good gun.
Thanks for the feedback. I was up to $250 on gunbroker.com for a Model 617 and still didn't meet the seller's reserve. I'll check local gun shops next.
