My only real experience with Mitsubishi has been with their rear projection video cubes - and they worked very well.
Mits. doesn't seem to make a mid-level home theater projector that I have seen, but they do have decent specs on what they have out for home theater.
For business... well, they have a full line up and I'm hard pressed to complain about most business projectors outside of Barco's crap.
Take a look at specific reviews at
http://www.projectorcentral.com which just has about the most good stuff on projectors specifically that you could hope for. Lots of good and worthless customer reviews.
Sorry I'm not more help.
What is your application you are using the projector for?
