for a couple of bucks i would say
http://www.opencrypt.com/ is a great cms.
or opensource would be
http://www.midgard-project.org
right now i am using postnuke and its a pain in the ass, but i have edited it so much that i dont want to switch to anything else as of yet. later on down the road i am hoping to switch to opencrypt because i does alot of what i had to alter right out of the box.
