Here are some websites that contain joomla extensions (modules, components, plugins and templates)extensions.joomla.orgwebmaster-tips.netjoomla24.com

I believe joomla is the best (1.5)Has lots of extensions (modules, templates, components and plugins)Easy to useContent management is more than excellent , you can add categories, sections and articles and add each directly to the menu.I haven't tried any of the paid CMSs, but joomla is enough.
