First of all, be wary of comparing RPTVs in a showroom - they are almost never calibrated properly and there is often too much ambient light.
That said, there are major differences between the Pioneer standard line and the Elite sets. The Elite sets have a very good de-interlacer (just like in progressive scan DVD players), liquid cooled lenses for better focus and detail, and a 6500 degree preset color temperature option. The biggest difference is the dot pitch of the screen, which is 0.52mm, which is the smallest dot pitch for a RPTV in the industry. This is what gives the Elite sets a CRT-like appearance, and you can move closer to the screen than with other sets and not see the screen structure. This is a very expensive feature and is one reason for the high cost of the Elite sets. You can buy this type of screen as an after-market piece for most RPTVs, but the cost is around $1500 to $2000, depending on screen size. Feel free to email me if you need more info.
