I agree with weagle99 re: early 3rd gen SAA. There are some good ones, but generally the quality of fit and finish is much lower than 1st or 2nd gen guns, and that's often really hard to tell just from pictures. The pictures may show a nice blue and beautiful case colours, but you really need to handle the gun to see some of the details.
Some of the issues that you want to look for are: the fit of the backstrap and trigger guard should be perfectly flush to the frame, you shouldn't be able to feel the joint; the radius of the "horns" on the top of the backstrap should match the radius of the hammer, and the top of the "horns" should blend and smoothly match the frame; all the edges should be straight and crisp, not soft or slightly rounded from over/careless polishing; there should be no end shake of the cylinder in the frame; if you are able to, try the action and see how smooth it is.
What's really eyeopening is if you have the opportunity to examine a high condition 1st gen SAA, and then compare it to a typical early 3rd gen SAA; the difference will jump out at you.
You can always have a rough action smoothed and tuned, but there's not much of anything you can do to correct poor fit and finish.
I've owned several early 3rd gen SAAs and a New Frontier, but I don't think that I'd buy another unless I could get it at a real steal. I'd rather save up a few more dollars and look for a 2nd gen, or a recent production SAA.
