Paul,
you can try Kicad. It is free and it is also a complete suite for PCB
design in Orcad style. There are versions for Linux and Windows (I'm
using the Linux one). Many libraries and worldwide support exists. Go to
http://iut-tice.ujf-grenoble.fr/kicad/
They have also a support forum at Yahoogroups.

Martin, OK1RR
