an lcd is the way to go IMO. look at this this way, either one is goona blow away the normal tv's, and if your goona spend the cash might as well enjoy it for more than a couple years. i went through months of research about a year ago, and went with an lcd and am glad i did.
if you buy at costco, they automatically extend the warranty to 2 years for free, and you can return the tv whithin 60 or 90 days no questions asked if you do not like it. that and their usually cheaper than most other stores. i strongly urge you to research whatever tv you are going to buy to see which ones produce a quality non hd picture, as some hd tv's will reproduce a whorrible "regular" picture.
