There is nothing around $2,500 DLP for no obvious reason at all. There should really be a DLP model which DOES compete with the Epson and Panasonic at that price range with motorized zoom, excellent lens shift, long zoom, and active iris. Unfortunately, DLP manufacturers just go cheap, cheap, cheap.
They can do this because the DLP technology itself is inherently better than LCD. It has, by far, the fastest response rate for any front projection technology with no real blurring or image degradation introduced by the chip set. The use of a single DLP chip means that you get a razor sharp image with cheaper optics which is a real plus for the consumer.
