I finally bought 2 of them

Well to be exact, I bought one. And then realize that the second one is better for me. So I exchange the first one with the second one.
Acer H6510BD http://www.projectorcentral.com/Acer-H6510BD.htm is the way to go.
However, my room has a width of 3.2 m and I want a REALLY BIG screen.
So I search for something similar but smaller throw radius.
So I exchange that with
BenQ W1080ST http://www.projectorcentral.com/BenQ-W1080ST.htm
More expensive. But I think I will be able to get a big 4 m wide TV I have always wanted to work peacefully.
Regular TV would have cost $5k and stuff. This projector only costs $1200.
Yes, the second one is more expensive. So it depends on where you want to put things. If you want to put it on a big room where you can afford some distance between the projector and the TV, then the first one is the way to go.
Note: I should have answered with something I recommend rather than actually bought. However, I finally bought... can be interpreted as I recommend .... I mean why would I buy something I don't think is good? Not sure how the mod would think.
