Aldo Uberti got his start making period correct movie prop guns for the Italian western movies - the so called 'spaghetti westerns', many with Clint Eastwood as 'The Man with no name'. They are now a very modern facility, making guns and parts on CNC machinery for several other companies. Their guns are good copies of the originals, including the actual finishes - CCH, blued, white, etc, are all as the originals. Ruger's blued guns look far worse - likely due to the poor prep of the bare metal - it should be quite slick, and you can see lines under even the Ruger 50th Anniversary models' finish I've seen. Sadly, their 'CCH' is an applied faux finish - a paint. I prefer SS anyway.
Parts procurement for Uberti's now is no more a problem than it is for Rugers. I actually think that the Uberti's parts may now be more easily interchanged than they were, due to the CNC production uniformity. I know of several folks with new Uberti's who have experienced zero problems - not so, unfortunately, with Rugers... they do have more QC issues. In fact, I consider them as 'works in progress' as delivered (That said, my last two revolver purchases were Rugers - and, yes, I got to work on them!). As Jim March said, they have addressed the variable nature of the chamber exit bores, but abandoned, at least for now, the .44 in their new Vaquero line. Sadly, the .44 Russian, the 'Original' centerfire metallic cartridge round, finds only the Uberti, etc, clone of the S&W #3 as a chambered example now.
I doubt you'll be unhappy with either... get the one that looks and feels good to you. Don't let a few extra bucks deter you... if you are like me, you'll keep it for a long time.
