HardwareZone.com has a great multimedia projector buying guide posted on their site. It explains the different technologies and what to look for.
Quote from the review:
“Most people relate projectors with movie theaters because of the large viewing screen. But if given a choice of a display device for movie viewing at home, most people would prefer a plasma TV instead of a projector. http://www.hardwarezone.com/ will discuss why a projector is not only the best choice for presentations in small classrooms and large conference rooms, but also the best choice for viewing movies at home.”
