I think DiscoPaul is posting drunk again. He likely meant that the 5020 is a grand more than the Samsung 50B450. Which makes sense, since it is a 1080p Pioneer with Kuro technology and the Samsung is a 1024 x 768 set sitting in their low-end line and using hand-me-down panel technology. Of course, the Samsung does have "Mega Contrast", which makes it look... well, like a television. The Samsung 4xx series are nice enough sets, my parents bought one for their bedroom and it works great. But even as overpriced as Pioneers are compared to the rest of the plasma market, there is easily $1000 worth of difference between those TVs given the differences in resolution, colour rendering, speakers and sound, image processing technology, screen quality, overall build quality, anti-glare filtering, etc.
Disco, I know you love the Samsungs, but even you know that comparing a 4-series plasma to a Kuro is like comparing an AMC Gremlin to a BMW M3.
