CODIN  I have used Bezipped since it was released. It has been very stable, and in most cases it yields a smaller archive then the built in zip functionality. The one feature that stands out for me, is the 'Create "Windows Friendly" archives' in preferences. In my office there is a mix of Windows/Mac users, and whenever I send an archive to a Windows user they always try to open the resource fork. My only feature request would be that the app auto-quits when I drag files to it.
