I just made the same decision. 'Worth' wasn't in the equation, since I'm not preparing the gun to sell and I don't mind spending money on something I intend to use and enjoy.
My gun has decent but finish worn barrels and it needs the stock refinished. Gun is tight, and is a good shooter. My decision was to overhaul the barrel set, and refinish the wood myself. The frame will be left as is.
Color restoration carries some risk. I've seen pictures of these guns cracked through the sear axle. This one has been happily shooting for years before I bought it, and I'm not going to trouble it.
