I'm looking at buying, very soon, a flat screen LCD set in the 37 to 42-inch range. I've been looking at Sony, Panasonic and other top brands and I'm told that there are two versions of LCD, one has a projection light in the rear and the other doesn't. The light has a life of 3 to 5 years and costs about $200 to replace. The other set is more expensive but has no light to replace. Just wondering if anyone here has suggestions on what's the best cost-value purchase. Thanks for any help you can give a technology-challenged senior.
