I'm considering buying a used CRT from Ebay or some other place. With the new advances in tech., would I be better off with a $2,000 used CRT or a $2,000 new DLP or LCD? I have an old Panasonic CRT now, but bulbs are old and power supply is going, so I know how to set them up. But I don't know anything about the new DLP's new technology? Is the picture better with a new DLP than a used CRT with say 4,000 or so hours on it?
