Gonna be real tough to spend a few million. Haven't heard of anyone breaking a PCB yet either, but obviously sample sizes are small. It's not that difficult to prevent a fuck up if you know the mechanics. It's when you get lazy/tired that you fuck yourself. If you're gonna be that anal, buy a bunch of Guttbusters because no matter who you go to, ms is always gonna be a thing and chance of fuckups will always be there. & considering most people won't advertise they can do it (for obvious reasons), I would just /w someone with a current one and see if they'll refer you to who did theirs.
Shits sold anyways, but for anyone else trying a PCB in the future ^.
