I am tired of reading post after post from people stating that the PHD8 is better, has a better picture than the PV-500. Aren't both of these Plasmas based on generation 8 electronics? Have any of you who claim that the PHD8 is better that the PV-500 removed the back cover of both units and compared electronics? I would venture to guess that they both share the same high quality electronics. Yeah, the PV-500 has tuners and speakers, but can anyone show evidence that Panasonic has skimped on the other electronics within the PV-500 to make it inferior to the PHD8? For example, I've read the following quotes from Liam, quote, “This plasma gives a better picture than the PV500 and is better for PC use by far.” “No, I mean the PHD8 gives a better picture than the PV500 and is more suited to PC use. It is Panasonic's more commercially oriented screen and far more suitable for higher-end installs and PC work.” Is the PHD8 truly better than the PV-500 just because it is the commercial model or is it just a cheaper substitute due to the lack of tuners and built-in speakers? Others post, a PHD8 and scaler gives you the best picture available, better than that of the PV-500. This is all well and good. Where do these scalers come from? They obviously don't come from Panasonic. So, some of us are saying that Panasonic builds the best Plasma display (PHD8), bar none, but to get a great picture, you have to purchase a scaler from another (European) manufacturer. If we compared Panasonic products alone, would the PHD8 still outperform the PV-500? I truly agree that the Panasonic commercial panel models such as the PHD8 look better than the PV-500, however I have yet to see anyone present any evidence that a stand alone PHD8 will provide a better picture than a PV-500. I am open to any factual data that can be provided by forum members that will confirm that a stand alone PHD8 is a better model than that of the PV-500.
