Netscape builds on the <a href="http://www.mozilla.org/">mozilla core</a> nowadays. So netscape and the mozilla browser its practicly the same program. AOL has added some to the netscape bundle and modded the setup, for example I think they removed mozillas default popupblocking. (added bloat / worse default settings ;) ..)
Leech the <a href="http://www.mozilla.org/releases/">Mozilla browser</a>
..or <a href="http://www.mozilla.org/projects/firebird/release-notes.html">Mozilla Firebird</a> (new design building on Mozilla browser components, kind of like netscape).
