There seems to be a huge buzz at the moment regarding Panasonic's PT AE-100 and I am very intereseted in it especially because it offers true progressive scan pictures. The only problem I face is that I've been hearing that LCD tubes in projectors don't lasts as long as tubes found in conventional CRT TVs. The dilema I now face, is that if I was to purchase a PT AE-100 and I was to use the projector on average between 3-6 hours a day (as well as watching DVD movies I also have an Xbox and enjoy shooting the Covenents in Halo ), how long would the LCD tubes last before I have to replace them? - I heard that replacement tubes are very expensive! I would appreciate any honest replies.
