the 80 inch tvs are the LE632 model. just for reference, the 60" sells for around $1400 and most of the stores have the 70" for $2000 this week.
its a nice enough tv especially for the price/size, but its probably closer to a 5 or 6 out of 10 on the over all picture quality scale. id caution anyone whos thinking of buying a 60+" tv to really consider their space. if its a large family or basement game room it will be fine, but if youre just trying to get the largest tv you can into a smallish room you will probably be dissapointed. standard def material (dvds) look horrible on an 80", and so does a lot of "hd" content. the mitigating factor is how far away you are sitting from it. the further the better it looks.
few companies are making LCD models above 46" now. so you're going to be buying either an LED or a plasma at 60+" for the same price the plasma tv you buy is going to be much higher quality, but you mentioned not wanting one. my general opinion is that on the lower end the LED tvs have too many extra issues (blooming, clouding, flashlighting - look these up).
Right now the prices on a lot of tv's are really lousy. The 60" Samsung D6000, our stores best selling tv of 2011, was $1500 Thanksgiving week. It's $2100 now. The good prices you find are on things that stores have already quit buying and are selling off their back inventory - making them harder to actually find new in a box.
My store has the 55" Sony NX720 for $1600 this week, and it's going down another $100 next week (if you can still find one). It was one of CNet's two editor's picks for 2011 (along with the Samsung D7000 plasma). I think of all the prices in our store that has to be the best one I've seen since Christmas.
A 60" Panasonic ST30 (plasma) is around $1500 and thats a great deal on an above average tv.
Most of Samsung's prices right now are pretty lousy. I think the stores still have a lot of stock on them and are trying to clear out some of the other brands before they get to their Samsung stock.
