Homebrew PCBs

I recently ran across a booklet that I had bought (online) a number of years 
ago that describes, in pretty good detail, a process for making PCBs with 
plated through holes.  The process it describes uses an electroless copper 
plating process to get copper onto the walls of the holes, then 
electroplating copper to deposit the final layer of copper, and finally, the 
photoresist application, developing and etching  The photoresist and 
developing chemicals that the author specifies in the booklet are rather 
expensive.
I have looked high and low on the web for any reference to this booklet, 
without success.  The booklet contains no copyright info, not even the 
author's name.  I've scanned the document and am willing to make it 
available to the group.  I'd like to get set up to try this process if 
someone could recommend some alternative photo chemicals (much less 
expensive) to use in the process.   I can see that this process could indeed 
produce some high quality multilayer boards, but for a hobbyist, the expense 
is just too high using the photo chemicals suggested in the document.
The original document specified Kepro chemicals, but I found that Kepro was 
transformed into D&L Products, Inc (Dalpro).  I updated the text to reflect 
current contact info.

I'll post the document to the files area, and would love to hear comments 
(pro and con).  The document is titled "The PTH Process For Homebrewers", 
and is a PDF document.
