Plenty of topics to read through, but if you do some looking around at etailers such as VisualApex and ProjectorPeople you will find that $1,500 doesn't actually buy you a 1080p projector at this time unless it is refurbished, or an older model.
Visual Apex does have last years Espon 1080 projector (not to be confused with the Epson 1080UB) available for $1600 plus a $300 mail in rebate, for a final cost of $1,300 plus it comes with a free replacement lamp. Good deal!
BenQ has also put up their W5000 projector from time to time as a refurb model in their clearance section...

Definitely a very good deal for the $1,300 or so that they sell it for.
But, you actually need to do a fair bit more planning before you can really pinpoint the exact projector you should be getting.
1. What is the size of the room it is going into?
2. Is it fully light controlled?
3. What kind of screen is going in?
4. How big is the screen?
5. How far away are people sitting from the screen?
6. What is your budget for audio?
7. What will be viewed on screen?
A good screen runs around $800 (
www.carada.com) or so, and if that's supposed to be included in the sub $2,000 budget, I would say that you have little to no chance to go to a 1080p projector.
One of the better projectors on the market at 1080p is the Epson 6500 which runs around $3,000. That's $1,000 more than you are looking to spend in total.
