I just went through the same decision-making process. After having finished my basement last winter, I wanted to replace my Sony LCD.
I saw some well set up/calibrated projectors in completely light controlled rooms and even had my wife (AKA, my opinion) with me.
We tried REALLY hard to like the projectors, but we both reached the same conclusions. Really big picture, but we were disappointed with the overall brightness, "pop" for color and the softness of the image in relation to a TV. Also, the idea of bulb replacement on top of the projector and a screen didn't raise my lumens.
Finally bought a 58" Panasonic plasma and we are thrilled with it. A lot of real estate and the clarity, definition and pop (without bulbs and screens) we were looking for.
It really boils down to budget and personal preference.
BTW - you may want to go to Projector Central and look at some reviews. That unit you mentioned on ecost doesn't usually show up in the top recommendations.
Good luck with it!
