All the suggestions are great choices.
A friend of mine and I went through a projector upgrade a year ago and we both settled on the JVC RS1 which also fits your budget. The RS2 came out last fall so prices on the RS1 have dropped accordingly. Its an incredible 1080p/24 performer with exceptional lumen output and very high contrast ratio. My friend has a bright room and he went with a 121" DaLite Hi-Matte White screen while I kept my 110" Vutec Silverstar. Another screen in your price range which matches well with that projector is the DaLite Hi Power.
