Hi Tei,
Eagle is by far the most popular free software.
Most vendors offer various types of demo packages. some limit time
of use (30 days) others limit no saving of files or other nonsense.
Check Olimex site for a list of 20 or more packages with links to
their sites.
WinQCad is probably the easiest to learn, but lacks some of the
expanded features of Eagle.
A hobbiest my never notice the difference.
Eagle limits board size, as does WinQCAD, but Eagle offers a larger
board area. 4 x 3? to Q's 2.35" x2.35"
