[Zope] who is using webdav to build zope site?

Hello I am just curious: I try to use webdav to edit my web-sites (it was looking more promising than the external editor). Up to now I have tried the Jedit Dav plugin and skunkdav. Skundav seams much more useful. Question: what is the best (free) webdav client/editor that you have used? Thanks Gilles
