Steve Gibson has an episode (#133 at
http://www.grc.com/securitynow.htm ) in which he discusses Truecrypt
with Leo Laporte.  In another webcast, though I don't recall which
one, they discuss the merits of PGP, the opensource equivalent
(http://www.gnupg.org/ ), and the weak encryption associated with
Winzip.  I guess it depends how strong you want the encryption to be.
According to Steve, Winzip encryption is easily broken.  I have
personal experience with Truecrypt only.
