I currently use the non-profit version of [Diptrace and have produced a few boards. It has a more familiar windows environment than Eagle, and is much faster on big schematics due to its hardware acceleration. It makes exporting gerber files simple and has built in preview software. The autorouter is pretty decent as well. The new version, 1.5, is great imo.
I have previously reviewed the old version (1.4) [here](Todds Spot: Diptrace PCB Design Software Review)](http://diptrace.com/)
