What are you wanting from your projector is what it comes down to. Some basic questions below so we can tgry and help you more.
Also does your budget include a screen or is it just for the projector?
Do you know if you plane on going with a 1.78:1 screen or a scope 2.35:1 screen?
What screen size are you aiming for?
How important is 3d to you? Have you seen 3d on a dlp? What is more important to you, the best 3d or black levels? Would you sacrifice black levels at all for what is more or less 'perfect' 3d?
What are the dimensions of the room you intend to use it in?
What is the room like? Is it light controlled, what color are the walls and ceiling?
Will you be watching just films, or will you be watching sports or playing games?
Two basic recommendations I would give is the Panasonic AE8000 if 3d is of minimal importance for you, especially if you are going with a scope screen as it has a zoom function and one that is automatic as well. If you are going with a 16:9 screen and you want the best 3d possible in this price range then I would recommend the Benq w7000. With the Benq w7000 the black levels aren't quite as good as the Panasonic but the image in 3d essentially ghost free, the benq w7000 also makes more noise then the ae8000 which in eco mode is more or less whisper quite (one of my favorite things about the ae8000 it can even be right on top of your head and you can barely hear it on eco mode). Be aware that whilst Panasonic make excellent product there customer service is notoriously bad at times.
I shall do my best to help where I can. I wouldn't recommend Epson due to past dealings and issues I have had with there projectors but many do like them, but0 I do think the panny and benq tend to be the leaders in this price range depending of course on what you are after.
