Money not being an issue, I'd get the Uberti. Not because it's any better than a Pietta, but it may be made closer to original specs (size, not metalurgy) and they hide the "black powder only" and some other irritating markings on the bottom of the barrel - hidden by the loading lever. I have mostly Piettas. I have an Uberti made 1858 revolving carbine only because Pietta doesn't offer one. For me, money is a consideration....
