This is from some dude on projectorcentral.com. $ 98,550 (MSRP)
I saw this baby with the 10K light in action at the Government Video Expo in Washington, D.C. in December 2005. It is immense. About four foot long, three foor wide, two foot tall. You ain't gonna hang this brute upside down, bat-like in your living room, trust me on that!
With respect to image quality, what can I say. The demo showed 35,000 Excel spread sheets concurrently. And when you walked up close to the screen, you could read the numbers in each and every one of hese 35,000 spreadsheets projected simultaneously. Try that trick with your $999 Best Buy projector!
The native resolution is app. 4,000 x 2,000, "4K" or 8.2 megapixel. The Digital Cinema Initiative won't eve go there until after 2010.
The projector weighs in at 282 pounds. There are two sturdy grab bars built into it front and back, so I suppose four hunks can lift it and move it about. But be careful on those stairs! You also need to have proper air ventilation (ir duct to the outside) for this baby.
