I presently have a sanyo PLVz 3000 which is rated at 1200 lumens and 65000:1 contrast ratio. I have had it brand new since Jan 2009 running the same bulb which has 1800hrs. So far there is no noted decrease in quality. Our room is a dedicated theater room. As far as the screen goes, we built one ourselves back in 2007 when using a matinee hd projector. We used popular wood for frame and braces and strectch black out cloth over frame. Then use 3" black felt tape for border. Cost of materials was $95.00. I have been to many a home using stuart firehawk screens that cost thousands and just do not see the difference other than I have a little mor money in my pocket. I run a 7.2 system. At the heart is my new Denon 3313 that replaced my Denon 889. The 889 is now used in our pool room. I hope this helps in your decision.
