I use gEDA/PCB. gEDA works best on Linux. Some people are using it
on MAC. For windows you would need Cygwin or run a virutal linux machine.

My gEDA information (which includes my PCB footprint library) is at

I been using LTSpice. Works great for me, but i normally don't do very big circuits.

Thanks for the suggestions!

I recently (2 days ago) started using KiCad and really like it. There are some good tutorials out there. I'd recommend joining the Kicad-Users Yahoo group in case you need to ask questions.
