Check out the DVDO DV50 Pro. They can be had for @1800$ as factory rebuilt units. They list for 3500$ or so. About the best out there without going to the Lumigen which is a couple of thousand more. I got mine through Advanced Lamps. The VP50 may also fit you needs. Under a thousand. You may find other prices by googleing DVDO . Hope this helps!
