Re: For HD TV & Sports viewing: 720p or 1080p?
It does not make much sense to buy a 720p projector if a 1080p projector is not that much more. I never bought any 720p displays once 1080p was available. Even though 1080p is not being broadcast, it does not mean that it will never be. Also, depending on your pre-amp or receiver you could up-convert to 1080p which is still better than up-converting to 720p. I think that on a screen size of ~9ft. as you are getting, you would see a difference between 720p and 1080p.
The ideal situation would be to see both projectors and A/B them on ~9ft. screen then you could really see if the difference in $ is worth it to you.
