In addition to the EH-TW4000 made by Epson, there was another projector recently announced by Mitsubishi, more exactly the WD500U-ST.
One of the good specifications of this model is that it only needs 28-inches of space, in order to project an image with a size of 50-inches. In other words, this is a good projector for small rooms and similar spaces. The feature list of the WD500U-ST include 2,100 lumens of brightness, a good resolution at 1280×800 pixels, and lastly, an 16:10 aspect ratio.
On the other hand, one of the bad details is the price which seems a it expensive – $1,700.
