I would personally recommend the BenQ W10000 which is getting solid reviews and has many of the features that you may really be after. Like it or not, DLP simply is a half step better with black levels than LCD is managing, and at the same time, tends to keep a bit more brightness on the screen with those black levels.
Throw into this that if you aren't retentive about cleaning the air filters on LCD you will end up destroying the polarizers inside and the LCD will start to look 'yellow' over time. This is often not covered under warranty.
Why the BenQ? Well, it's a couple grand more than the competing LCD projectors, but it includes lens shift, a good zoom range, and a THREE YEAR warranty standard. As a DLP projector it should not have a air filter to clean which will lower your maintenance time, and should increase reliability.
The biggest issue? Perhaps the throw distance.
