I waited a long time to find a "deal" on a 617. I never really did and just ended up buying a nice one the popped up locally. No regrets and I wish I had found / gotten one sooner. I was hoping for a 4" but ended up with a 6" and absolutely love it. I don't think they will go down in value so the sooner you get one the sooner you can enjoy it regardless of price.
A dab of nail polish for the sight, Hogue wood grips and a lighter rebound spring round out the only changes. It LOVES ammo.....
