Jess, if you would like a second opinion on your prospective new camera, take a look at this...
http://www.steves-digicams.com/2008_reviews/canon_a590is.htmlIt sounds like Steve was very impressed with the A590! He quoted a retail price of $179.99, so if you found it at Circuit City for less, I'd think seriously about buying it if I were you. In fact I'm thinking about getting one too, maybe just after Christmas is over.
Read through his review when you have a moment. He covers everything on the camera, along with many pictures, including the menu displays. And you can also see sample images he took with the A590.
