I use Wing IDE for my python / zope development.
At home the $35 personal edition, at work the more expensive professional
You can really get to edge with it: Zope Debugging, code folding, easy access to
library documentation, in app python shell, customizable.
I do not have shares in this product :) It's just very suitable to program
Hope it is any help to you.
