FYI, Got a flyer from Michaels (craft store) and they had a product called a YUDU for just north of $200 us.
http://www.whatdoyudu.com/products/default.aspxIts sort of an all in one unit for screen printing on T-shirts, but I wonder if it could have any application on DYI pcb's for solder mask etc.
Its sort of of an all in one box that is exposure box, dryer, screen holder. The web site has a video on its use. They use some sort of dry film to activate the screen, water developed but use a chemical to strip and reuse the screen.
