I always found the best combination was a photo resist method, with a small CNC machine for drilling and routing the PCB. precision and accuracy is all about alignment, so i built alignment guides into all my printouts. I uploaded some photos of a one + the alignment guides I used, i even did nickel plating and a silkscreen on this one... https://imgur.com/a/GNZKaMK https://imgur.com/a/GNZKaMK heres a short video of the CNC drilling machine too, it was homemade https://www.youtube.com/watch?v=NiIWB1PsAg8 https://www.youtube.com/watch?v=NiIWB1PsAg8 used to take maybe 1-2 hours start to finish to manufacture a full PCB
