PowerArchiver claims to be the ultimate freeware archive utility for Windows 95/98/ME/NT/2000. It has built-in compression for ZIP(including Quake III PK3, JAR - JavaARchiver, OWK and REP files), CAB, LHA (LZH), TAR, TAR.GZ, TAR.BZ2 and BH (BlakHole) plus built-in decompression for ZIP, CAB, LHA, RAR, ACE, ARJ, TAR, GZIP, BZIP2, ARC, ZOO, BH and more. All that and a skinnable toolbar.
