I agree, you have to give more info , bro. Best 2 D for gaming, tv shows, blu ray, computer use, in batcave, or in room with lights on, with big screen.
Tell us your room and what you are gonna do with your PJ, what you will watch, screen size, room size, how dark is the room. Because some would be good for batcave but not for living room, and some would be good for blu ray but not as good for gaming.
Now, you could go to projectorreviews.com and look over their 2012, or 2011 yearly round up, and he does give best 2d, and best in 3d, and best PJ that does 3d/2d both good , etc ... maybe start there and figure out what exactly you would be doing with your PJ.
Also, some PJ'a are geared towards portable use with built in speakers and tons of inputs/outputs and some are just for ceiling mount and to be used in batcave only. Do you see why the other guy said hard to say what the best 2d model is? Without saying how you would use the PJ, can't really say, because it might not be best for you.
