Homebrew PCBs

MikeZ_Photo_Etching in files section show my latest progress in Photo 
Etching. In reality, the PCBs look perfect and very expensive.

Gentlemen, I appreciate your help in guiding me thru the maze of Heat 
Transfer and Photoetching and I feel being very profficient and 100% 
reliable in both methods. 

In 30 minutes I can have a PCB etched and dry ready for soldering for 
the cost of a PCB plus few pennies. I am not making it up.

Which conveniently brings me to the next question: where in US is the 
cheapest source of PCBs? Mike

PS I despise the use of special paper at $1.50 or $1 a piece.
