Hi, We are currently in the process of finishing our basement and are adding a home theater room approx 11x17. I am looking for any suggestions on what front projector system I should buy. I have between 10,000-12,000 to spend on the projector. The theater center near me recommended the Dwin Transvition, but I am concerned about the low contrast specs. From the specs, the Sharpvision XV-Z9000U looks good, but is 800 lumens in a dedicated theater room enough? I would welcome any help.
