I use crimson editor, it combines a text editor with syntax highlights and an FTP client.
When i saw that you could parse the PHP in the crimson editor, i immidiately said "that's the one for me!". But then, after realising it wont parse html, or anything else, I was kind of bummed. :(
I think I'll stick with php designer or pspad, until a better one comes along.
I'm desperate for textmate to be available on windows and not only mac!
