I saw this on EETimes a few weeks ago it's a link to a link to the Instrucatble It's a good article but they dont's go in to to much depth about the actual etching process. Also I would of thought that under etching may well become a problem at smaller sizes.
Personally I use copper backed Mylar that you can get for about £10 for an A4 sheet then do a conventional photo etch.
