The method's great for one-offs or perhaps producing a couple of PCBs. I
wouldn't dream of using it for more than that - it's just too
time consuming, and sometimes I have to fix the odd broken track due to a
pin hole.

If you're wanting to make a board in quantity, it's best to use a
commercial PCB maker. I've used Olimex for doing two-off Eurocard sized
boards (double sided), the results were good, and I used PCB Cart to make
10 4-layer boards - their prices were very good, the boards were
electrically tested, and the quality is excellent. People I know have used
PCB Train, and have lots of good things to say about them - they also do
include electrical testing on boards of 4 layers and more.
