Nice logo - I like it!
In regards to your pricing, i think you are selling yourself a bit short (sorry guys) Might want to check out other such lasercut sets from gpm and such to compare prices. $4 for a pre-printed model??? You must have found a really inexpensive printer for that... will it even cover your costs? Need to see how many pages the final model is as well to get a true estimate of the kit cost for the pre-print.
For the electronic version that wont be quite so important
