I would say value wise its in the same ballpark, question is if you want the muzzleloader barrel. As far as the encore goes I love mine, have .50cal, 270win and .223rem barrels for the frame. The stainless and camo versions are little more expensive than the blued and regular stocks. If your not planning to use the muzzleloading barrel I'd probably say keep the Sako as well.
But then again if your interested in single shot pistols, you can buy the pistol grip and take off the rifle stock and buy another pistol barrel for 200, and have a complete different gun.
