I purchased a 14-2 4" .357mag on Gunbroker for $295 a while back. It came in the original box with all the literature and wrench. It had never been fired, just spent its life sitting in a dresser.
It's been fired plenty now- I've always been a DW fan. Wrenches are available. I wouldn't go over $250 for one if the finish couldn't make 'very good'. Many aged Dan's turn a 'purple' kind of color as they age- some find it OK, big turn-off to others. Still a great handgun.
