http://www.pspad.com/ - I actually use 1stPage 2000 from EVRSOFT though - STILL waiting for the next version to be anything other than vapourware.
PSPAD has had considerable praise as a general text editor with HTML and other code enhancements.
Actually though, a lot of stuff, I edit it in as if it was notepad - really ought to make more use of the abilty to have code snippets to paste in - I like to know the structure, and I truly hate bloated, unreadable, illogical generated code.
