If you get one built up from the same maker, you might save a little if you could find the action for a low price. Or if you get a complete gun, say a 700 BDL or a PSS you could sell the parts you're not going to need and save yourself a few bucks that way. Regardless, we're probably only talking about a couple hundred bucks at best.
And I agree also that GA Precision is a great riflesmith. Their rifles are among the best I've tried. This includes some Robars, AI's and Chandlers.
