In what way is direct inkjet more fiddly?  If you mean by aligning things, 
I can handle that.  Most of the stuff I lay out is single-layer anyhow. 
I've thought of the photo process, but the price of pre-coated boards 
scares me off.  I'd like to be able to cut a piece of board for what I'm 
up to and not have to waste an entire larger board for that.  How about 
spray-on resist?

I had a modified GBC laminator of the sort that Pulsar advocated.  I 
haven't a clue where it wound up.  Pulsar suggests that the laminator 
works with their product, but not with Press-n-Peel.  I used an iron last 
night with Press-n-Peel and absolutely nothing transferred.
