If you are making the plunge into designing your own boards, another package to consider (instead of Fritzing, which not only has a very limited parts database, but making new parts is anything but easy) is KiCAD. http://www.kicad-pcb.org/display/KICAD/KiCad+EDA+Software+Suite IMHO it is a very good piece of software, and is FOSS. The parts library isn't as extensive as the commercial offerings, but the parts editor is about as simple as the big guys (unlike Fritzing), and there is active community support. Just remember, any decent EDA suite will have a strong learning curve but that is because properly designing a PCB is an exacting process.
To be fair to Fritzing, it is still in beta...
