Over the last few years I've been using WinQcad for both personal and professional projects. I found it easy to learn, and it's free up to quite a large size - I've never had a project too big for the free version. If you get stuck, you do need to buy it in order to get support, but the cost is quite small compared to other professional grade stuff (don't get turned off by the amateurish icons). It does nice schematic capture, comes with a large library of devices and footprints, an amazing auto-router, and it generates the Gerber files most board shops prefer, or acurate PDFs if you want to roll your own.

Highly recommended by a happy user that has no association with the company.
