My old man won an uberti cattleman in a raffle and I think for a colt copy they are superb. You are essentially buying an italian made colt anyway since they bought all the tooling from them when colt upgraded their shop.
Yeah cimaron is good too but if you are going to go that route a ruger vaquero might be your cup o tea then, and they are made in this country, plus I have never heard of anyone bashing a vaquero. However if you want an open top or remington looking SA, I think cimmaron or EMF are the way to go if you are looking for something different. Also if you get on the waiting list for a brand new colt, you are essentially waiting for an Uberti thats been slicked up by colt since colt buys the frames from uberti now. Go figure.
