I also will buy one. Have you considered leaving off the "White Tower" lettering so that individual modelers could add their own signage?
Then what would you do with the tower deco? There is the option of slicing off the letters and sanding the surface smooth. Part of the appeal of the model is that the intricate lettering is included.
Once the model is debugged, it will be available for sale through both the ESM and Shapeways sites. It will be announced here as well as other boards, Facebook and the front page of the ESM website.
