PCB etching and layout

[Steven Varner]

Hi (synth-diy),

I'm doing my PCB's as outlined in Electronotes PCC.  
That is I'm painting on the copper a design very 
similar to the circuit diagram, etching, then surface 
mounting the components.

A. If anyone else is doing this, what type of paint 
works best?  I've heard etch resist pens don't last 
long.

B. What do you use to remove the paint after etching 
(what is most effective)?

C. If I do decide to do a PCB layout, does anyone 
know a layout program for Macintosh?  I want cheap 
(ie. shareware) software if possible.  I haven't 
found any on the net as yet.

Thanks
