DTML and Python Editor?

[Bo]

I'm teaching myself Python & Zope. I'd really like to find a free 
programming environment to work in.


My options seem to be

http://www.zope.org/Members/Caseman/ExternalEditor
Zope product to enable an external Editor in Zope



http://www.editplus.com/index.html
$30
Syntax hilighting through plug in file


http://www.chami.com/html-kit/
free
Syntax Hilighting and custom word completion

Xemacs has dtml support from the python.org site. Although this has a 
learning curve is it worth the effort??? I like the multi platform feature 
but I chiefly use windows right now. 

Even slickedit would be an option but its expensive.


Does anyone with work experience in Zope and Python have any advice to 
share? I'd like to learn one environment for all this sort of work if 
possible -- that would let me concentrate on the language not the 
interface.

ps

What of the newer ZPE???? XMLish zope extensions??

what is the most full featured???
