Ron, the newer Plasmas do not generate as much heat as the old ones, but they still generate a lot more than an LCD or DLP will generate. The picture is better, and the screen has a longer life, but there is still a finite amount of time that the screen will last. An LCD will last much much longer than a Plasma, but the picture is no where near as vivid. Both Plasma and LCD have a limited viewing angle. Too far to the side and you start seeing a negative image. A DLP picture is in the middle of the 2. Closer to the Plasma than the LCD. They use a bulb (LED in a lot of new models) to light through a series of color wheels and then reflected off of millions of tiny mirrors. The bulbs (like mine) have a finite life as well, but cost about $100 to replace. The bulbs have to warm up and generally right at startup, there is a bluing effect until it warms up. The LED does not have to warm and does not have the bluing effect. The LED also consumes less power than the older bulb variety.
The avs forum that bomelia posted is a good forum for research. A lot of experts on there. I joined that site years ago, but I haven't visited in a long while and can't remember my login.
It is still one of my first stops to do research before I buy a new product.
