First off, I would just like to clarify that an LED TV is in fact an LCD TV. The reason it is referred to as an LED TV is because it uses LED backlighting instead of a bulb. But they are both LCD screens.

Whether the added cost of an LED TV is worth the added contrast and power savings is completely up to you.
