I used to work for Radio Shack and we sold TV's (we were independently owned). I would avoid a plasma TV. They don't last as long as LCD or LED TV's. The difference between LCD and LED is the lighting in the screen. With LCD, if a light bulb goes out, it will affect the picture on your TV. With LED (the type I bought and love it), the screen has thousands of tiny lightbulbs and if 1 goes out, you will never know. It does not affect the picture at all. LED may be more expensive but it will use less elecricity and runs cooler, too. It is amazing how much heat those TV's can put out. The store where I used to work sold many more LED than LCD TV's because of the energy factor. Also, the higher the number of pixels, the better the picture. 1080P has a brighter, clearer picturte than a 720P TV does. I hope this helps.
