I am setting my HT and I need to decide which projector is the best value. Are the most expensive JVC and Sony models worth the extra money? My room is 20 feet long x 17 feet wide x 9 feet height. Budget is not an issue but I would like to get the projector that provides the most value for the buck. If I can save some money and get equal or comparable value, I would rather spend the remaining money in something else. Thanks in advance for any advice.
