D-back in .38
I know I'm repeating myself, but i'm bringing pics to the argument now.
You have to hold one to know just how nice they are. Pics don't do it justice. And they are almost too nice to be carried. A real gentleman's gun rather than a working gun like a DS or J-frame. Also, many of these came out with 2.5" barrel, which with the target sights, and vent-rib, probably help your aim considerably.
They ARE approaching or even exceed Python prices, but you asked for the best.
Last one I saw in close to NIB shape was $960 INCLUDING not just the box, but the huge ding some knucklehead manage to put in the front sight and a scratch on the sideplate. This shop consistently has the lowest prices in the area too. I've always made out well, but had to pass on that deal for sure.
