There are an ever increasing number of places that will do pretty good quick turn boards. The fact that
you can get 4 layer 10x10 cm boards with 4/4 mil rules / 8 mil holes for < $20 each delivered in under
two weeks amazes me.Yes that’s a 10 piece price. Yes it includes framed steel stencils. Not so long ago
your cheapest option would have charged you $300 simply to set up the board (== minimum test charge).
The two framed stencils would have cost more than the whole order does now.

This was a single-sided board - I had absolutely no way to line up a two-sided design even if through-hole plating would have been an option (of course, it wouldn’t have). No solder resist, no silk screen.
