I think a big issue/ question very much worth aiming at ...
which was grazed in passing by Boemien...
what about the possibility of monthly payments?

And for that matter ...
How close are we now to assembly, production and shipping?...
and when would total payment due be required by?..
honestly...
no exact date required...roughly is more than adequate...
weeks...month...months...1/4 of a year...1/2 a year?
(I'm not in any way slamming a lengthy timespan....)
the more time ...could be better...
especially "if" the price (with fees) stays at the estimated...or possibly increases...
it would give breathing room to many... to play catch up.

@hxka - possibly ...it is quite possible you are correct ..it may take alot more ...

@swordfish II -Looks like you've got a win-win position there.

-if it fails (which I personally do not believe is going to happen) due to a lack of enough people willing to commit when it was needed ...(speaking for myself.. ) your (and to all others thinking the same) commitment and support to help make this happen was appreciated.
(I don't think a sarcasm emoticon is necessary here ...I think I made it thick enough in statement for it to be apparent.)

-if it succeeds (which I personally do believe is going to happen) ...I wish you all the best thinking you'll be able to just "order" one when the ship is sailing from port and shipping is commencing...like it is a Dell laptop waiting... pre-assembled just for you... in the warehouse.
and while on this topic... including a response simultaneously to stevenc's comment
I think reading how difficult it is going to be to source parts that are becoming harder and rarer by the day to get (as it is now)..creating just a 100 units is a grand idea...doesn't mean it will be possible to make more later though... due to a (more than likely) lack of needed parts.
