This is my final warning, there are too many GOOD single action revolvers to be spending money on a cowboy. I get the impression you really want these, so when you get them I hope they are the good ones.
You know you could get Berettas probably for less than that. Ubertis are good guns, heck, if you want a pair of SAA's I have a pair of Jagers I'd let you have for way less than that!
My honest opinion is that if you want a Colt, get a Colt, not this bastardization. It was a good idea poorly executed. If you want clones, there are better for less. If you like transfer bars, Ruger, Beretta, and I think Great Western's.
