I am debating for the same thing.
I mainly watch movies during night in family room, so light control might not be a huge problem. The 92" DLP projection TV looks pretty good and price is good. But it is huge and I can hardly find a stand for it. My family room is 20' x 24' with 10' ceiling. Front projector is good and costs less if I DIY a 110" screen and use a low end projector, but I don't have a "real" TV in family room then.
