At the end of the day, nothing beats photoetching. Use your laser to print the artwork on a transparency and expose it to UV light, develop it and etch it. Simple.

Actually, the copper foil technique was developed precisely because it is easier than the heat transfer method, and produces vastly superior results. It is very dificult for most people to get consistent results with the TEC sheets (and similar products), and the very fact that the toner is transferred twice limits the minimum reliable trace width. This new method promises high quality prototype PCB's with a minimum of fuss. CIAO - Martin.
