I went new TV shopping in Greenwood, IN today. Visited a Circuit City, HH Gregg, Best Buy and a Sears store. I had been all set to just purchase a 36″ flat screen TV, but from the moment that I saw the projection TVs, I was in love with their crisp, bright picture. WOW! My last stop was a Sears store and I really liked the Hitachi 46F500. At $1899, it blows my whole tax refund, but I'm sooooo temped to go for it. Anyone have any experience with this model or projection TVs in general? My friend who went with me, told me that they don't last as long as regular TVs. Is this true?
