My very first board was double-sided.  I’m using Pulsar’s product.  It  
wasn’t perfect, but I’m very happy with it.  I used 2-sided copper  
clad, fully etched the first side with shelf paper on the other side,  
and then drilled out a couple of holes for components on opposite  
corners.  Then I prepared the 2nd piece of transfer paper and poked a  
pin through the appropriate places and used the pin to line up the  
paper on the board.  I applied contact paper to the first side and  
etched again.  It really came out very, very well.
