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.
