I figure if there are enough kb'rs or people kb'rs know I could sell a few to bank-roll a CNC engraver. Size is 250mm wide, by about 220mm high. Price would probably be between 70 and 150 depending on whether people want the edge-lit bit at the bottom, and how much time is required to touch up the images.
