Summary: I recently looked into getting a projector, and found myself looking at the Optoma HD series. There were a bewildering array of models to chose form but I was told that all of the 720p optoma projectors are very similar, and not to look too closely at the manufacturers specs as you'll want to tweak the settings to get the best picture anyway, so 13000 lumens becomes more like 500 lumens when you set it up for watching movies in a darkened room.
Summary: Once upon a time setting up a home cinema was only thought to be for the mega rich, but things have changed over the last 8 yeasr in a big way. We currently have Kef speakers paired up to a Denon amp, all we needed was a half decent projector to complete our home theater experience. We play our DVDs and Blu Rays through our Playstation. When we received it we placed it on our ceiling approx.
Pros: Half the price of an HD TV,super quality, comes with a good box and carry handle
Summary: I bought this projector in 2008 and I am using it every day with no issues up to now. My Lamp is coming up to 3000 hours but other than that excellent. Use it on my PS3 to watch BlueRays and play games and it has been great.
Summary: Fantastic value for money; this projector punches above its weight. I am projecting onto a 2 metre wide (not sure what the diagonal measurement is) screen and getting fantastic results - MUCH sharper than the image you get in a cinema. The level of detail you see (e.g. people's faces) is just amazing. The only negative comment I have relates to bright white images (e.g. clouds) which sometimes become ever so slightly distorted/pixelated.
