Charles Morris and I have been working to create
an
equivalent for the KC8A
Nice, generally though the demand for something is
much greater if you actually have it ready to ship (in
case your preorder responses are low, don't get
discouraged). Looks like your front panel and parts cost are
constant with quantity, but your pc board drops
greatly with quantity. If I were you I would just
order 20 or so pc boards and let the buyers order the
parts and panel separately (as needed, some buyers may
not want the panel, others may already have most of
the parts).
The problem with that is that it forces us to front hundreds
of dollars, with no indication that we'll ever get it back.
I already have boards sitting around from several projects,
representing hundreds of dollars of investment on my part,
that may never "sell" (even at cost).
It is a lot better for us to have some idea of the demand,
so we can mitigate how much "over-investment" we want to do.
Though you are right, that if we found someone who would pick
up the overhead cost of a board order ($200 each time), we
would be way ahead. (Anyone know of a shop that can do a
double-sided 16" board with solder mask and without a steep
setup charge?)
The other major ticket item for this project is the front
plate. Anyone know where we can get those done inexpensively?

I had used their "no touch" prototyping service. Unfortunately, it has
an 10.9" length limit. Our boards are each 15.5" long.
Their other services are normally higher than the shop that I usually
use. However, I see that they are having some 40% off promotion, which
helps a lot. Their setup costs appear to be about $153, instead of $200
for the shop I was thinking of.
Thanks!

What about switches for the front panel, that is a big expense too.

Just what do you have?

If you try Canada you can get 14x17 inch boards done.

What about a local machine shop?

put in
"metal fabrication" in your google or search engine of your
choice and at least here in Orange County, Ca it brings up all the
local choices I know of. YMMV, but you could send drawings for
a quote to each. A call to each place explaining how you will buy
would help you get a more reasonable quote.
They usually have the same constraint on their quoting as the board
houses do. You actually pay the most at a board house for the holes
and cuts in a PC board than you do for the rest of it after a certain
point.
Unless you add on premium testing, or unless you have a complicated
multi layer board with special problems with the fab, you will find
that the cost you can't reduce is the number of holes you make.
Same goes for the metal work. Also most fab shops dont like to
set up for 5 pieces, so the price will be spread over a few pieces
for the setup, and run the cost up there.
For a professional job i'd figure that you'd pay about $50 to $100
each for 1 to 5 pieces. Less than that would be good.
