CMS for bloggers

So, I'm still investigating a CMS (Content Management System) for the libraries web editors. A CMS is just a easy way to get content onto the web, without having to do much in the way of design. Blogger in some senses is a very primitive (primitive because it is limited in what it can do) CMS. Unfortunately, my quick and informal survey of web editors has yielded, ummm... not much. A lot of them still seem to use Dreamweaver and templates (our current setup), a few Contribute, and then every thing in the middle, including (shudder) FrontPage.

As for myself, I am in a similiar situation. It's time to either renew my license with ee or skip on to something else. sigh.
I want something easy to use (ee is!) with a photo gallery (ee has but I'm not using it for a variety of reasons) and something that is not so expensive for a small commerical license. I'm currently operating under the personal license but it is definitely restrictive in terms of what I can do. So.
I want one thing to do everything. That would sound like a cms, no? One design software that I can control with css, that supports flexibility (alot of it) in terms of templating.

Here's some interesting research:

Plus: Excellent tech support

Movable Type (I used the free version, before all of the changes to a more commerical product)
