Screen Scraping Application for use with Online Sportsbooks

I need an application that I can view data from numberous online sportsbooks showing me their current lines. The application will need to autoupdate and show realtime lines in no less than 1 minute intervals, also being able to highlight recent changes. It will pull realtime data from up to 20+ online sportsbooks and display it on one screen for me. Programmers with a working knowledge of sports betting a plus.
