Homebrew PCBs

I'm curious how many people here are applying their own dry film 
photoresists. I've stumbled upon a method that seems to work half 
reasonably. Rather that discuss it here I wrote up a web page.

I'm interested in what other techniques people use since I've never 
tried one of those office hot roll laminators. Are these machines "fool 
proof" or have they got problems like bubbles and wrinkles ? The film's 
stickiness makes it difficult to work with.
