1080p projectors are still up there in price well above $1000 but the bigger improvement is light output and contrast ratios. They have improved that dramatically and even the 720p projectors of today will blow away what you have now.

Ok well, Here is your current projector. Its 1500 lumens with a contrast ratio of 2500:1
Here is the Panasonic PT AX200U. Its less expensive and is 2000 lumen at 6000:1 contrast ratio.
How large of a screen do you have?

That Panasonic for the price is hard to beat. With a 102" screen you would be hard pressed to see a difference between a 720p projector and a lower end 1080p projector.

Some say over 100" but others say 110" and it depends on alot of other things like screen design and the projector its self. I myself would love to upgrade my old Sanyo Z2 720p as its only 800 lumen but that would be a very tough sell to the wife. The good 1080p projectors are well out of my reach.

I personally would not go larger than 110", I sit 12' away (front row) and have a 96" and find that very nice and I dont find myself moving my head much to see the entire movie.
