I would not buy a projector of that cost without seriously considering what I want to use it for.
The projector was clearly designed as a business grade projector with that level of brightness and the resolution and 4:3 aspect ratio. So, there may be some deficiencies in the quality of on board video processing that the projector can do.
Motion artifacts, poor deinterlacing, lots of pixelation, lousy handling of 16:9 material, poor color rendition of video, HD quality scaled down for non-HD performance, and other things are all possible drawbacks for projectors designed to go in a board room and primarily display Power Point presentations with half the lights in the room turned on.
It is not an inexpensive projector either so I think I would first check out
www.projectorcentral.com and think about how you will be using the projector and what type of room it is going into and then if you are still interested, check the return policy where you buy it to make darn sure you can return it if you are not thrilled with it.
Most people don't test drive cars without reading lots of reviews and taking a test drive, a projector that costs half or a third the price of some cars should not be bought with no return policy if it turns out to be a lemon either.
