I have been doing a lot of home work and have narrowed it down to 3. The Runco710 have seen a demo very impressed. The Sharp XV-Z12000 read great things about this one, but can't find any to demo. The BenQ8700 heard that it is the same machine as the runco for half the price, if so does that include the lenses. Any help with my decision be be appreciated. note: I will be projecting onto a Carada high contrast or Stewart Firehawk screen 110"or 116"diagonal if this makes a difference for projectors.
