after month of pricing and feature comparison 's , I opt for the Epson 71c lcd projector , since it be the best price xga -lrb- 1024x768 -rrb- projector available . there be less expensive model with lower resolution -lrb- VGA -rrb- , and other xga model that go as high as $ 14,000.00 ! factor to consider be : lumen -lrb- brightness -rrb- , resolution , video input -lrb- vga\/svga\/s-vid \/ hdtv -rrb- , lifespan of the bulb -lrb- hour -rrb- , and cost of the bulb -lrb- replacement bulb for this model on the internet be -lrb- price range -rrb- -rrb- .  the most common application for projector be business presentation , so if this be you use , the weight may be important .  I have a hdtv tuner card and a dvd player on my home pc , so connect the Epson to my home pc turn my living room into a high Definition Theater ! you can connect directly to you pc or , as I do , use a SVGA cable splitter . with the splitter , I can use the regular monitor without use the projector in order to conserve the lamp life -lrb- rate at 1500 hour -rrb- .  the Epson can turn the image upside down , if you need to mount it from the ceiling . keystone correction compensate for a angled projection by turn the trapezoidal image back into a rectangular image .  the unit have function flawlessly -lrb- get it in January 02 -rrb- . since I have not use other projector , I can not compare it with other unit ; but I have no regret with this product . order thru Amazon.com be convenient and painless , no sale tax , and free shipping !
