Cool write up, getting initial bill shock from 2 layer to the 4+ layer PCBs is a rite of passage :)
Went with wrong board house. JLC seems to run 6 layer promo for 2 years now. This board is $36 for 5, $100 gets you 50 pcbs.
The next step up is HDI. I knew it was (still) expensive, but I did not realize it was a cost multiplier, not adder :-)
