I don't know of anyone doing this, but places like "Danbury Mint" offer some nice pre-builts, but they are "pricey". Unless you are absolutely hopeless at modelbuilding, the more you build the better you get ! I've been addicted to the hobby for over 50 years and can't begin to tell you how bad I was when I started. I remember getting an Aurora candy apple red ME-109, and not knowing what decals were, I cut 'em out and glued them on !!
