When I read here, it seems that rear projector LCP and DLP TV's have many problems. Plasmas dont seem to have as many, but the old fashioned CRT rear projector tv, such as the Hitachi 46F500 or the Samsung HCR4755W 47" CRTRP, doesnt have near the problems. I know the hitachi has a good picture and both or HD, but only the samsung has the hd tuner. Is it better to save the money and buy the larger TV? Advise???
