Homebrew PCBs

Hi all,
	I was just wondering how many people here would like to make their own 
plated through hole double sided boards. How far are hobbyists willing 
to go ? The main question is if this extra step is worth the amount of 
chemicals and equipment needed to make plated through. I had the desire 
to make plated boards for a long time but only because I find both the 
chemistry and electronics side interesting. From what I have found with 
experiments, is that the process can be done at home if you are prepared 
to put in the effort. There is a lot setting up with the equipment such 
as plating tanks, etching tanks, making holes conductive, applying dry 
film photoresists and then there is the equipment for analyzing the 
chemistry, not to mention the learning curve. About the only good news 
is that the chemistry is relatively low cost and the toxicity is about 
the same as conventional copper etching solutions (copper is a toxic 
heavy metal). The ultimate aim would be 4 layer boards, but that raises 
a whole new set of hurdles.

reagrds,
