So price estimate:
Unit price USD = (200 + 7*100 000) / (units)
And what about tax and wages etc. etc. etc?
There is absolutely no point doing it that way these days.
It'd be far, far cheaper to cost reduce the minimig and do a bigger run of these.
Something more like Jeri's C64 in a joystick is much more likely to work and most importantly - actually sell in good numbers.
