Well, I'd recommend Trumpeter's Saratoga, if you'd like to build a carrier, and you don't want to build something dirty. In her pre-war configuration, she was kept pretty clean, haze grey, mahogany-stained flight deck, and a nice complement of yellow-wings aircraft. You could also build the kit as the Lexington from the same period. Out of the box, it's a decent kit, but you can add more photo-etch and really turn out a nice model.
