Guys, IMO we're discounting several Very Large factors when we automatically assume that the price is 'way outta line in comparison to the base model Italian replica.
First of all, the Italians have been at it long enough to have long ago amortized not only their initial design, engineering and tooling costs, but all of the subsequent technology upgrading as well.
Secondly, aside from a couple of special order models at much higher prices, most of the authenticity in the Italian replicas is basically cosmetic. Compared directly to a genuine period Remington, they differ in some significant details. They're slightly smaller in most dimensions and the rifling is very different, just to name a couple of the biggest.
Third, the level of craftsmanship displayed in terms of smooth function and quality of fitting/finishing on even the nicest of their standard production 1858 replicas that I've seen tends to be 'spotty' at best. Less frequent on the Uberti's, granted, but still not exactly what I'd call stellar.
Even with CAD/CNC technology, setting up a line for a whole new item isn't a simple or inexpensive process. Engineering costs money, programming costs money, debugging both during prototype runs costs more money, skilled labor costs money to find and retain and so does training those production and assembly folks in the details needed for the new product.
All of that has to be recouped before any profit is realized, and the smaller the projected number of units they'll sell is, the higher the percentage of those costs each one will have to reflect in the pricing.
Neither the SAA or the Remingtons are modern designs, and even with the advances in manufacturing technology they aren't machines where everything can just be dropped in or screwed-on, it'll all work together in perfect harmony, feel as slick as snot on a glass doorknob and shoot where you point it.
If they make the Remingtons to the same standards of quality and authenticity that their SSA's exhibit they'll surpass everything else out there, and not just in price.
"Value" is a term that's always relative and always highly subjective. Only the guy shelling out the money can tell you "why" something's worth what he spent to him.
