If you look at my forum ICON you might guess where my interest may be with the models. I have both the LA and OHIO class "boats".
Now granted that the construction of a model sub versus that of an AFV or plane is not nearly as complex or detailed. But I really like the models and they fit nicely in my collection. I got them a while ago at a local auction so I am afraid I cannot tell you about their business etiquette or professionalism.
If you try to compare them against K&C, FL, CS, or even plastic or resin kits from companies like Dragon, Revell, I would think that you are missing their “niche”.
