Just a note to those people who said 7zX wasn't working for them. You have to drag files and drop them on the 7zX icon for it to work and work it will. I tested compressing a text file, a graphic image and a folder of mixed files. Everything went off without a hitch. Combine 7zX with The Unarchiver (see http://www.versiontracker.com/dyn/moreinfo/macosx/30810 ) and you'll be as happy as a clam. Stuff it, Stuffit.
