I used PSPad for years, but have recently been turned onto Komodo Edit: http://www.activestate.com/komodo_edit
It's not a full-fledged IDE, but it's about as close as you can get... and it's available on Windows, Mac, and Linux, for free. -- <http://forum.pspad.com/read.php?2,50353,50358> PSPad freeware editor http://www.pspad.com
