Difficult, if not impossible to put a 'general' cost on refinishing a stock....
IMO a refinished stock has less value than an original stock....
In the scheme of things, a refinished stock will diminish the collector value, but increase the life of the stock. Also, I've seen some "re-finished" stocks that were far nicer than they were from the factory. True collectors scoff at a refinished stock, but someone that wants to use it in the field will welcome the reduction in price and be thankful it will endure more harsh conditions...
