The ratings on picture speed quality ( less blurr with high speed objects such as football or racing) is
Plasma #1
DLP #2
LCD #3
That is the reason we went with Plasma, was gonna go with DLP but found out the plasma is quickest with picture blur. I still like the DLP picture, but the TV's are larger in cabinet size (deeper) and the DLP looses picture quality when viewed from an angle.
Go to your local appliance dealer and just set and watch all three types, from straight on, at an angle and in different light, but also ask them to hook each up to normal cable, satilite, and to rabbit ears. If they want to make a sale they will do that. Don't just go by the picture they show you on the TV cause most are hooked up to a pre programed HD CD they have choosen as the best pic and color to show off the set.
