I found a great little site tonight called Widgetbox.
In their own words
Widgetbox is a directory and syndication platform for web widgets for blogs and other web pages. Our widgets work with TypePad, WordPress, Blogger, MySpace as well as most other blogs, sidebars or websites. No plug-ins are needed, and they’re free!
it has hundreds of great add ons like page rank, digg and delicious badgets etc for your blog however the best widget for me is the ability to add your own site as a widget. Essentially, the widget allows readers you to list the latest posts from your blog – basically an rss feed scroller however its really simple to use.
I recommend dropping by and scrummaging around til you find something you like
