Patrick R, as a modeller, we would definitely like to see rare variants released. But as a startup company, this is a detour away from our core product development.
As ripley had stated, companies like S&S Models, had released conversion kits to compliment our product line which we found it extremely helpful. Our goal is to release what we called "base kits" with the most common variants, and let customer build on top of what we have designed. A good example is the SdKfz 251 with the upcoming releases of several expansion kits from us!
