In the real world, a million units is way larger than the actual market size, and ten thousand is more realistic (maybe still too large). Seeing how producing a relatively large quantity of units is not an option, those machines are going to turn out to be pretty expensive

Makes you wish you were stinkin' rich

You're making too many assumptions to come up with a per unit cost of a re-production. Do you really expect someone on this forum to research all the variables and give you a discrete price for a product that has no demand in the real world? Or are you just asking a hypothetical question?
It should be possible to come up with a reasonable estimate
