Cadsoft
(
www.cadsoft.de or
www.cadsoftusa.com) has a nice PCB CAD tool
(Eagle CAD). There's a freeware version, but it's limited in
schematic and PCB size. There's also a low cost non-profit version
that's still somewhat limited but a lot less, it might work for you.
I've been using an older version for some time now, it's quite a nice
product.
I just checked the site, there is no Hobbiest pricing there.
I guess the state of of homebrew now days is a PIC and a few leds
on 2x3 inch board.
The Freeware version is the hobby version. The next level up is the
"Non-Profit" version. Beyond that they assume you are doing real work (that
pays for itself somehow) and want you to subsidize their development with
real $$$ for licensing.
I checked the website, and the Freeware and Non-Profit licenses are both
still available at
