comparrison box for joomla php website.

I require a comparison script like the one at <[login to view URL]> another version is also at <[login to view URL]> this is to fit on a joomla php page and read from an xml file unless a better file format can be advised. the site this is to go on is <[login to view URL]> and should fit on the main page. username testuser password testuser I would prefer a mock up of what will be delivered when bidding please. this bid is for a finished item that can be dropped straight on to the front page. Preferably using ajax...... I am open to suggestions so feel free to post a comment. thanks.
