I have a chance to buy one of these that has been lightly used in an office environment. This is a 60" rear projection TV that will also accept computer input. I am told that this TVs were very expensive new but don't really have an idea of todays value or quality compared to the "new stuff". Do any of you have experience with these? Would this make a good primary TV? Are these ready for HDTV? Any ideas what a "great deal" price would be?
