Pedigree drawing programs

[Melanie Mahtani]

I am looking for a list of programs, both freebies and
commercial, for drawing pedigrees.  Preference is for 
mac-compatible software, flexible about input format.

It would be helpful to also get a critique of available
software, if anyone has used multiple programs.

Thanks in advance,
