Homebrew PCBs

Hi again.

Well so much for that - I was going to continue trying to get a good 
development but I might as well try something else as I need to get some 
PCBs made soon.
I have just finished an email to a knowledgeable fellow, to whom I admitted 
that the new photoresist from RS may as well have been a can of whipped 
cream for all the good it does.

The reason I am back here again is that I have found (whilst looking for 
Riston PCB's) Press 'n' Peel film.
Simply (as they say) copy or print the artwork onto this film with a laser 
printer, Iron onto the blank PCB, peel off the film, and etch - simple.

Has anyone used this before and is it as good as they say?

Also I see another chemical, Ammonium Persulphate, that I have never used - 
anyone use this and does it have any advantages over Ferric Chloride?

cheers,

Daryl.
