You can't just buy any old flat screen and expect it to be wonderful, no matter how much you pay for it.
There are a lot of factors to consider. Pioneer had the Kuro, and that was the cat's ass. It all comes down to whether or not the television can be calibrated to hit standards. Most can't.
Since the demise of the Kuro, Panasonic makes the most accurate televisions on the market, and they calibrate wonderfully. Almost everything else either has a drastic compromise or poor calibration abilities. The screens just won't meet the standard, no matter how hard you try.
There are only a few reasons to buy an LCD. If you leave the television on all the time, when channels may not be displaying full screen images, a plasma can burn in over time. If you are concerned about a little extra heat and energy usage, an LCD is easier on the wallet, but it's going to take a while to pay for itself, as LCDs are generally more expensive for a good model. If your television is in an incredibly bright room, sometimes a plasma isn't the answer depending on how the room is arranged. If you plan on using it as a computer monitor, definitely go with an LCD to avoid the burn in issues.
That motion control crap on LCDs doesn't work. Still images can appear to be static images, and fast motion just doesn't display properly. While the new LED side-lit models display darker blacks, they clip the lower end in the process. Plasma televisions can display proper blacks, leaving detail alive at the same time. LCDs generally have shortcomings in color reproduction as well, while plasmas do not. The viewing angle issues on LCDs has improved, however.
The technology used in these new 3D systems has been around for ages. I had shutter glasses and a 3D computer setup in 1996. It sucked then, and it sucks now, but people want it, so the manufacturers are trying to make it work. It's never going to. Up the frequencies all you want, you are still dealing with adding or removing frames, and that always fucks things up. Color reproduction goes out the window and the flicker never goes away.
An LCD is for people who
need an LCD. It is not superior technology.
This is what I've got, in the 50 inch size.

I'm about to buy another, but it's going to be used in a different way, with frequent static images, so it will be an LCD.
Panasonic has always been the brand to beat. They pull no punches in their televisions. Kuro was in another class. Right below it, however, was Panasonic. Just below Panasonic, Toshiba hung out for a very long time.
Sony is overrated, and Samsung cuts corners.
