I purchased my Sharp 632U this month from AllTimeTVs online for under 3500$. It was a very successful purchase....friendly, non-aggressive salesman who knew his stuff, great price, no hidden costs. They shipped the day after I ordered the tv, and I purchased a White Glove Delivery so that I could see the tv running before the shipping guys left the house.
I was going to by locally, but Best Buy was reluctant to match online prices and so full of themselves and overpriced on their warranty that I said the hell with it and researched a reliable online seller.
It was really the best online experience I've ever had with a big ticket item. There is a small freight handling/insurance fee, but it is clearly mentioned online in the details...it's amazing how many negative reviews are posted due to people's lack of reading comprehension skills these days.
Anyways, this very nice, and huge tv is still on sale online at AllTimeTVs as of this posting on Wed. Nov. 21. They are a real company offering this great tv at an amazing price, and shipped mine off about as quickly as was humanly possible.
