Opening .msg files in Mac OS X

Hello,

How do I open .msg files on the Mac? I received a collection of these files on a flash drive when I went to a conference. From my research, these files are generated from Outlook. I tried TNEF's Enough, but that didn't retrieve any usable data. What program can I install on my Mac to view these files? Please don't tell me to install Outlook. I don't like Microsoft Office and don't want to waste gigs of disk space.
