Summary: I have owned this projector for 2 years now. I always run the fan at it's high setting and it is STILL pretty quiet. I have this unit on about 8 hours per day, everyday. I use it for websurfing, HD TV viewing and HD movie watching. The $300 for a replacement lamp is cheap for how long they last, I have just now put in my second lamp and will gladly do so again when this one goes out. I figure less than 50 cents a day for a WALL-Size screen is very affordable.
