You can always add a external Darbee to any projector. Some people think they work well others think they are worthless. I doubt any of those Optima's will look any better then the BenQ. The Sony 45es is known for its excellent motion handling and image processing so that might be the right direction for a upgrade. I assume sports are watched from a cable feed that is most likely highly compressed 720p so as the saying goes crap in crap out.
