   In fact, I have not been able to find precoated
board (photoresist
  coated) in the .050" thickness.  So I will either need to use a
  liquid photoresist or try a toner transfer system. 
Personally, I would avoid liquid photoresist and use dry film in its
place. You could contact Fred at Far Circuits
(http://www.farcircuits.net/) as he will supply boards precoated with
dry film photoresist. URL for supplies is
http://www.farcircuits.net/supplies.htm. According to the site, he will
supply 0.047 material laminated with Dupont PM115 photo resist film. 
Now he tells me?!  :-)   I'm already down the road with the uncoated 
.047" board.   If that yields poor results I will try Far Circuits. 
Thank you for that source.   I searched all over the place and never 
found that page.  Sigh.
