The Vudu BX100 retails for $300, but a limited-time promotion includes a $200 movie credit for those who purchase the unit at Best Buy.So basically you’re paying $100 for the machine, which allows you to tap to more than 1,100 HD and HDX movie rentals at $4-6 a pop.  This is even more movies than what XBOX Live Marketplace and Apple iTunes offer at the moment.  This is due to Vudu’s  commitment to add 150 HD flicks per week in October, and it’s still going strong.  So are you ready to jump to HD movie downloads or are you sticking with Blu-ray?
