about the same size room as mine.
Is $8K just for the projector?
Do you plan to watch just in the dark, or with other lights on.
That will dictate a lot as to which projector to get.
My advice (for what its worth), and assuming this is your first projector.
Plan on $3K or so for speakers, receiver and dvd.
Another $1500 for a great screen.
Another $1500-2000 for cables, install and setup.
Then I would get a good 720p pj for anywhere from $2K-4K.
With those prices, you could easily get a "WOW" system.
The sony is a great pj for $7500, but its not good for every setup.
I dont think that getting a 1080 pj is needed now, and you can always upgrade in a few years with the money saved. The market is in flux, and anything you buy now will be worth less than 1/2 in a year.
By the way, the sharp 2000 is a good pj for under $3K, but I think there is better now. If I were going with the sharp, I would get the equivilent sharp DT400 for $2999 at costco. With costco, you could use the pj for months, or even much longer and take it back for a full refund if you dont like it for ANY REASON!.
