Homebrew PCBs

I gave myself a Christmas present, the current edition of the 
ARRL's "Hints and Kinks".  The author recommends Staedler Lumocolor 
318's which he fits into one of the refillable plotter pens.  (That 
is, he cuts the marker with a utility knife and fits it, tip and all, 
into the carcass of refillable pen.  (I guess that it's kind of 
messy, but that hasn't stopped any of us in the past.)

HP7475 pcb construction:

FAST AND EASY PRINTED CIRCUIT BOARDS
Like many hams, I prefer to build some of my gear. I started etching 
my own PC boards several years ago, and I have tried 
several methods. The least expensive approach is hand-drawing the 
pattern on the board with a permanent marker. This can be 
very time consuming and does not easily permit a good parts density, 
so it wastes copper.

I've been using positive photo sensitized board. If you use a PCB 
layout and print transparencies in positive it is possible to get 8 
mil lines every day. 

BTW I'm selling a PCB and schematic capture program at eBay

Currently the first bids stands at 1 penny.. but that may be too much 
to ask.. !
