You might check out Target 3001. They have a free version, the only catch
is you must use their partner's PCB service. I used the service once,
excellent results, prices a bit on the high side. The cost for a paid
version that lets you do Gerber output is pretty reasonable.

The only thing good about eagle is has a schematic
package.
I am still looking for a free PCB and a free Schematic entry
program because that for me is bigger than eagle's demo size.
While waiting for PCB's now may be the time to evaluate some
programs before you create your sim's.

PS I remember somebody put a linux? system on a sim. If you can
find that page it may help you with your design.
