Best Bang for buck projector

I would not buy the Dell 1410X projector!  We have purchased over 40 of them in the past two years at my school and 18 of those have gone out in less than a year and we are not overly using them. They overheat  VERY quickly and shut off as a safety precaution. That is not conducive to teaching children. One teacher even puts her coffee mug near the projector and with the extreme amount of heat (within only a matter of minutes), it keeps her coffee warm. Also, speckles of what looks like snow (probably dust) on the interior lens has damaged the view on many of them. It just gets worse until you can't see anything. Several have gotten horizontal lines across the screen within only months of using them.

We have returned many of the projectors to be fixed, but now our warranty has run out and wouldn't you know it 5 more died the same month right after warranty was up. According to our IT department, Dell wants to charge an outrageous amount of money just to look at it--something like $250 (not totally sure) plus charge for any parts it would need replacing. That puts you close to the price of a new projector! And money we don't have to purchase them! 

For a school who has a very limited budget, this is an injustice. A recall should have been placed on this model and money refunded or projectors replaced. The tech people on the phone claim "no one else has complained of these problems." I find that hard to believe.
