Anyway, Finn, the program I use is express PCB, you can get it at

Yes!!  A lot of people are using this nice free program!!

Cheers,

 yes that program is good i use it too for my boards but use it to print on
press and peel and make my own boards.
it must be easy to use as i manage it.
only thing is to make your own there is a trick to get it to print correctly
but thats just colours of layers
cheers
