I'd like to chime in with a "third option" for PCB CAD: Fritzing. http://fritzing.org/home/ It's not nearly as full-featured as KiCad, Eagle, etc, but it has a lot going for it: -Totally free, open source, unlimited board sizes -Very easy to learn - I picked it up in an evening -Seamless forward/back annotations - PCB and schematic are continuously synchronized automatically -There's also a "breadboard view" that is synced with your PCB and schematic. Kind of a gimmick, but good for tutorials (Sparkfun uses it for this) -Integrated code editor -Single integrated tool -Multiplatform There are some drawbacks of course: -Making your own parts is rather painful -Only does 2 layers -Not frequently updated -Part library is limited It also has an autorouter, which works reasonably though probably not as advanced as in other tools (I haven't compared) Worth looking at if you're a beginner/casual hobbyist/maker .
