I wonder about things like component video inputs and all the screen adjustment controls I get on a commercially available projector. I scanned the web site and couldn't find any real detail there.
You can drive your projector with a third party adaptor... or you can drive it with a computer with DVD... or you can buy a LCD screen that has TV inputs (including component video) (I did)... or you can find a DVD player that has DVI or XVGA output (I did.)
Oh, lamp costs are between $20 and $35 for lamps that last 20,000 hours instead of $295 - $500 for lamps that last 1000 to 2000 hours. More expensive lamps can go for 4000 hours... but that still translates as only 2.5 years or so before you gotta buy a lamp (If you ignore the steady reduction in lumen output!)
Incidentally, the keystone controls on most projectors are digital... they make the changes in screen dimensions digitally. The Lumenlab design does it optically.
