from peter - "If a 100 (or even more, like 200 or even 250) quit that would for sure affect the price of the device. " - in reference to the new estimated price tag.
I concur considering the revised price...based on just the figure alone ...many may immediately come to the conclusion it is beyond them...

hence my suggestion of relief from that in the shape and form of understanding when board/ device completion rough-estimated time-frame would be... so people know what they are wrestling with and can realistically figure a budget and save toward it or possibly pay installments...
More people are apt to stay.. instead of leave... if there is a rough timeline to budget toward or methods in place to reduce the pressure to something manageable
