I didn't think you were starting any arguments. It's great to see people talking or debating about USFA firearms. I am personally hooked on USFA firearms. If you find an FFL/Gunsmith Ma & Pa Shop that you can have a good relationship with, you'll find you can get your USFAs for a good price all the time, and in pristine condition. Some of the Big Box stores let every Tom, Dick or Harry play with SAAs and let them get scratched up, as well as making people premiums for them.
As far as pricing goes, USFA kept prices pretty much the same since February/2006 until April/2007. That is very reasonable. I would worry more if prices stayed stagnant for too long. When they do, it could mean pricing was way to high to begin with, or they are pumping out higher quantities to keep down unit costs, which usually quality begins to suffer.
As far as the differences between the Premium SAA and the Pre-Wars go, Pre-War SAAs have Color Cased Hammers & Armory Blue finish, the correct use of assembly numbers in hidden places, the option of a serial number to replicate an original, and the option of the "V" Notch rear sight and blade front sight along with a Black Powder frame, or the Square Notch rear and square front blade along with a cross-pin Frame to more closely replicate an original SAA.
Either gun will make you very happy as USFA firearms are great shooting Sixguns that are well built.
