One program that hasn't been mentioned yet is the one I use: DZSoft's Perl Editor.
It's a windows based editor that integrates with ActiveState and highlights syntax (which is customizable). The two things I particularly like are the fact that I can do a quick syntax check with the F-12 key and it's got a browser so you can see what CGI programs will look like as well.
All in all, worth every penny of the $49 or so that I paid for it (shareware).
Now if they just had it for Linux...
There is no emoticon for what I'm feeling now.
