What price are you looking at for each? How far will the lens be from the screen? How high above or below the screen will the lens be? the HD71 is really bright and will have a more washed out image unless you have a huge screen. Both projectors can only accept 1080i input, but who cares as they can only output 720p. If you really want a projector that accepts 1080p in that price range look at the Panasonic ax200.
