This looks interesting. I like the autorouting function, simpler than some software. I've only looked at the basic video demonstration so far. I'd need to know how easy it is to change track widths and pad /hole sizes. Presently I use Express PCB and Express SCH, more freeware. I like these two though there are limitations; for example, it isn't easy to lay down tracks at 45 degree angles, whereas with pad2pad this is a built-in. Certainly worth considering and it looks easy to use.
Nice young lady presenting the video, too...
Thanks, Col!
