I'm the webmaster for Miss Louisiana (Miss America--come visit us!
www.misslouisiana.org), and I use Macromedia Contribute and HoTMetaL Pro for my site maintenance. Sadly, the latter is no longer available since Softquad was taken over by Corel.
Contribute, however, requires no HTML knowledge other than the basics. It runs ~$75 or so...much cheaper than Dreamweaver, but it's good for site maintenance and can be learned easily.
Hope this helps. Let us know how your search and site design go.
