Homebrew PCBs

that was printed from a PDF of the GameBoy PIO cartridge here
http://marc.rawer.de/Gameboy/   top layer

I ran it with just the default settings on a HP LJ1200 from a cold start
the copper foil is a strip of 1.25" wide slug and snail tape from
the lawn and garden dept. ,for some reason slugs wont crawl over
copper but they love aluminum especially if its a beer can
(mmmmm... beer :)
once it was on the paper I gave it a scrub with a scotchbrite pad
to rough it up a bit to hold the toner and gave it a swipe with acetone
to clean off any oil 

offhand I'm thinking something smaller might work better
maybe the Pic sip from the Eagle single sided tutorial or a 
basic stamp clone or SIMM Stick format board ,something like that

or it might just take a tew tweaks to the settings like you say 
I was thinking of puting the tape on a transparency sheet to make
a sort of home brew flex circuit
