Don't overlook the Remington Navy in .36 calibre, it's a real sweetheat and much more powerful than you think. It's really .375 calibre, and the Remingtons have long/deep chambers. A full load of 777 will put it right up there power wise with a 1860 .44 Colt. On the other hand, with a light load it's a really nice plinker, and a good grouse gun too, if you do any type of big game hunting where there are also grouse running around.
But again, before I ever owned one, I used to think the .36 was a real "weak sister" to the .44's. Not true, they are actually quite powerful.
I have a Uberti, which are supposed to be very high quality, or better than the rest, but I have heard that this is not ALWAYS true. My example is very nice for sure, and shoots to point of aim. It is also extremely accurate.
I also have an Euro-Arms 1860 Colt, and it is of higher quality than most other 1860 Colt replicas I have seen or owned. Be warned though, that the open top Colt's won't take full loads of 777 like the full frame guns will. (Ruger or Remingtons) On the other hand, the Remingtons and Ruger don't point, handle and balence like the Colts do.
On Pedersoli, I've never owned or shot/seen one of their revolvers, but I have a Pedersoli Brown Bess musket that I am really, seriously impressed with.
