481176 Wordpress plug in that feeds from Craigslist

Hello, I'm looking to have a plugin/widget that auto updates using craigslist to notify the site of new post in designated cities using specific keywords. Example. If I want all post in the Dallas gigs section that contain the phrase "web design" the title of that gig should automatically be updated within my sidebar on the wordpress site. Example 2. If I want to find a playstation 3 in New York, all post with the phrase "playstation 3" should automatically post on my wordpress sidebar. Its very similar to the idea of a RSS feed. If you have questions, please ask them. I'm ready to start this project right away.
