i want to buy my son a 42 inch tv for his living room for x-mas. they now have a 36 crt so any tv will be a huge upgrade. plus save a ton of space. there are some incredible deals on 42 plasmas=panny=499. rca =399. there living room is usaully darker then most with not much direct light but an unshaded sliding glass door 20 ft. to one side bringing in medium light to tv area.would this work well or do plasma users need to keep all light out when using?
