External HTML editor for RH

Hi all,

I would be interested in hearing of any external HTML editors that RH users like using with RH instead of its internal editor.

Somebody please suggest a free (or almost free) HTML editor that features lots of features, eg, hiliting, split Design/HTML windows, clean XHTML code and checker.

Wasn't there once some browser called Mozila? Or was it called Netscape?

Tia
