I think the "#1 missing product" is entirely dependent on your modeling interest. I model Santa Fe in the mid 1950's. I run a little bit of steam for fun, but by 1955 steam was gone. I'm not sure there is a "missing model" for my era and interest. It used to be the Alco "alligators", but that those have now been manufactured. For someone modeling any steam era, there are probably more "holes" than models available. The nature of the beast is that it seemed every railroad had to have their own style of motive power. There seemed to be no such thing as off the shelf production models until the advent of the diesel.
