[sdiy] pcb question

[mostaware at mac.com]

I'v started using OdmondPCB for OSX and it seems OK.  good for free.  
another mac users out there?  what are you using?

here's my question.  What's a good trace width for a diy project?  I 
currently have my design set to 30 mil for trace width, the default was 
10 which is far too thin in my mind.  I will be attempting to use 
DynaArt Design's toner transfer system to lay down my design to the 
board.  anyone else try this?  If it doesn't turn out so well, i just 
just go over it with a sharpie, right?
