Any suggestions/hints/experience/links regarding the best/easiest way to clone
a (two-sided) PCB, i.e. create a Gerber or equivalent file from a PCB layout

Easiest? Throw some money at having someone do the work f
I reverse engineer boards as a hobby i produce full schematics and can

I have the boards produced in china. should be cheaper now that china is

just takes time and money
