I got nothing better to do on a Bank Holiday Friday:
Sony VPL-VW50 - 47x17x39cm -
11kg -
15,000:1 -
900 ANSI -
3,000 hours
Mitsubishi HC5000 - 33x12x35cm - 5.6kg - 10,000:1 - 1,000 ANSI -
5,000 hours
Epson TW1000 - 40x12x30 - 5.6kg -
12,000:1 - 1,200 ANSI - 2,000 hours
Panasonic PT-AE1000 - 46x13x30 - 7.2kg - 11,000:1 - 1,100 ANSI - ?? hours
Optoma HD81 - 41x11x31 - 4.5kg - 10,000:1 -
1,400 ANSI - 2,000 hours
BenQ W9000 - 49x19x39 - 9.4kg - 8,500:1 - 1,200 ANSI -
3,000 hours
JVC DLA-HD1 - 45x17x41 - 11kg -
15,000:1 -
700 ANSI - 2,000 hours
Hours are in low lamp mode (ECO)
ANSI is in high lamp mode
Dimensions are all in Centimeters, weights are all in Kilograms
So it depends what you want,
If you want brightness (plan to use it in a medium light room) then the Optoma/BenQ/Epson should be considered and the Sony/JVC ignored.
And none of these figures tell you anything about picture quality, ease of use etc..
For example the Optoma has no lens shift, so you have to mount it center to your screen, the Sony has a good following on this forum, the Epson is the latest of the group to hit the market and you can (while stocks last) get a free PS3 with it.
Also worth finding out is the size of image you can get from the distance you have, as this will vary quite a bit.
Time to get googlin
And once you have it narrowed down to 2 or 3, then it's time to get ringing around to find someone who can let you demo them, preferably in the same location on the same day with the same sources.
