new to the world of projectors, altho i have spent some time researching them lately, here and at different forums, and was hoping someone might be able to point me in the direction of a workhorse projector, a brad or unit known to hold up under fairly heavy use, perhaps 5-6 hours a day, 5 days a week. it seems that a lot of the projectors i've researched are owned by folks who have complained that they have run into problems when it comes to heavy use, or even not so heavy use, say about 4 hours a day, 3 times a week. i'm not looking for a reference projector, it will be used in a commercial environment, but i would like it to be 1080p capable and accept hdmi. $1,500-$2,000 is about as high as i would like to go, but if there is such an animal for less i'd certainly be interested as well. any help would be very much appreciated.
