Homebrew PCBs

It's been awhile since I've worked on my printer and it's all gummed up 
again (damn Epson print heads) I was looking at the 
Epson Stylus C120 which seems to have a slightly better droplet size (3 
picoliters). Has anybody tried this one for a mod? I havn't looked at 
one in the flesh yet but all the "C" models seem to be all about the 
same. I was working on a flat bed with a built in heater but LIFE got 
in the way. I see Volkan is very busy in that reguard I hope to be too.
