I've had a love/hate thing going with SA revolvers for years. I like the idea, love the looks, but for some reason they just don't fit my hand well. I've owned five Ruger SAs and have finally given up on them. I bought an Uberti Cattleman last fall. I'm having better luck with it than the Rugers, but the jury is still out.
As far as DA wheelguns, I like Colts and one of my favorite carry guns is my Detective Special. But if you think S&Ws are expensive, check the going prices for the ponies.

I don't care much for the current Ruger offerings. The GP100 is typical Ruger. A fine gun, built like a tank, but has the ergonomics of a brick.
I always had a great fondness for the old Security Six and regreted never buying one when they were still being made. I finally took care of that mistake at a gun show last year. I truely believe that the biggest mistake Ruger ever made was dropping the "Six" line of revolvers.
