Homebrew PCBs

Steve,
      I went back and looked at my first message. It looks more like 
an ad than what I was trying to say. What I wanted to say is selling 
a built machine is very hard. Even if you charged $500 each the 
profit would be small. Several people made one of my machines and 
sold it on Ebay. They made $25 profit not counting their time! 


                                           John
