Since you mention Eagle and having the limited license, have you ever tried KiCAD (http://www.kicad-pcb.org/)? I don't know very much about Eagle, KiCAD, or Eavle vs. KiCAD but it looks like it's free and without size limitations.

If you have a comment on KiCAD I would love to hear it. There more that I have reread my thread on "beyond the breadboard" the more that I think I may want to try PCB layout on CAD software and photoetching or maybe even having a board manufactured. To do that I understand I will have to learn Eagle, KiCAD, or something similar that outputs to the GERBER file format, right?
