While shopping today for a new entertainment center my wife told me for my 30th birthday she is going to buy me a HDTV. Well since my birhday is not until January I got a long wait but I need to know what I need to look for. I read sound&vision, home theater magazine, and sometime audio/video interiors and look at all the different topics posted here but I am still confused on what to look for. I heard of line doubling, comb filters, 1080i (which I understand). I was planning on only getting a HDTV-ready for now until more programming is ready. To let you know what else I am working with- I have a Denon-4800 receiver, Sony dvp-7000 DVD player, Dish Network receiver(basic), and Def Tech speakers. I would like to get a HDTV in the 56-64in range depending on price and performance. I think my budget might be around 4,000.
