I have the Encore 50cal ML and can't say enough about it.Shoots well right out of the box. The reason I choose the Encore was the capability to interchange barrels. I know they are pricey but some day it will be in my sons hands and if he chooses not to use it as a ML he can buy the barrel of his choice.
I will say one thing, its well worth the money to buy one of the new style Bellm hammer extenders for it. Getting a thumb on the hammer can be a little tight if you add a scope.
