The only other Windows one that I know of personally is http://www.freepcb.com/
which is free. I gather there is also a router package as well. I know nothing about it apart from having seen it.
I find myself in the situation of really not being happy with anything that doesn't tie the schematic and PCB together, provide forward and reverse annotation, ECO generation, BOM generation. and other features like variant management. Sadly nothing short of a commercial packages offers it. There is a reason why you get something for your money with commercial EDA software.
