By the way, prices for these sets (and all HDTVs) are in a freefall at the moment; great time to be a buyer! Many stores, including BB, will negotiate on price (I have done this). The *lowest* price will often be some place on the net you've never heard of with a terrible resellerratings.com score (if any), but there should be no problem talking BB or CC down to, say, Amazon's price.
And make sure you know what kind of 30-day, etc. price guarantee whoever you buy from offers, because at the rate prices are moving you will almost certainly have some money coming to you - make sure you know the terms and how you have to contact them to take advantage of that!
