DITTO!  I have OFTEN needed "onesy-twosey" PCB's with PTH, and have had to 
use "jumper wires", eyelets, or have 'em made by the local PCB house for $450 
each!  Seems plating-through should be within the realm of us ol' 
home-brewers who can make a double-sided board, if we just knew the steps, 
and where to get the chemistry to plate the holes before etching.

You DO know, doncha, that the PTH is done FIRST, then "SOLDER-plating" of the 
desired pattern (including through the holes!), and etch LAST, with chemistry 
that will etch copper, but NOT "solder".

Someone TELL us how!  GOOD topic!
