The first thing you do is choose between plasma and LCD or a projector. They each have their pros and cons and your choice would depend on your needs. I'd say go plasma for a big screen but if you go LCD and your pockets are deep, I'd consider the Samsung 950 with the LED back lighting or even their 81F which you may find a a good price. It may even have deeper blacks than the Pioneer and Panasonic plasmas.
Besides CNet for reviews, I like this
