I like JEDIT for my perl IDE-editor.

PLUSES - FREE, runs anywhere java does, very cusomizable with plugins, tabbed editing, custom code folding, edit via ftp or sftp, color parsing for TONS of languages,TAG support, all commands via cusomimizable keystokes, cusomtizable menus,

NEGATIVES - A bit slow on startup, addictive.

It really is addictive, once you get going you'll find it hard to switch back to your old editor.
I swear they should be giving me kickbacks... :)
