I started with photo-resist PCB, I found it to be very expensive, that's why
I switched to toner transfer. Yeah, it's more tedious trying to pass paper
through a printer, but I save money in the long run and right now that is a
concern.
Now if you would point me to a source of photo-resist liquid that I could
just spray onto copper-clad PCB, I'd reconsider the whole thing. But
you're still faced with the same alignment problems with double-sided PCBs.
My solution would be to use transparencies, tape them into a sandwich and
use a double-sided exposure setup. I used transparencies on my laser
printers and was very satisfied with the results. But you also have to deal
with one extra chemical.
I just like to explore all avenues first, and then make a decision after
I've heard reports on 'all' techniques. Right now toner transfer is my
favourite, but if I can print directly onto thin substrate, I might switch
to that technique. But I just won a Epson C84 on EBay for $10.50 this
morning and I'm going to test this process.

It is kind of funny how some of us refuse to go down the path of
photosensitive boards (myself being in this category). I don't know
why, I used have a darkroom and develop photos and such. However,
using it for PCBs just isn't my "cup of tea" I guess.
I believe there will be a variety of options for doing double sided
with ink jets. It's just a matter of getting things going and seeing
how everything works out.
