The PV8 would score over Full HD LCDs for SD content, no doubt about that. But a TV is not a daily/weekly purchase and I'm pretty sure Full HD content will be taking over, might be slowly but nevertheless will take over eventually. When that happens a Full HD LCD or Plasma will be better than HD Ready. If you plan to get another TV in a year or two then go with HD Ready for now. If Full HD is available for the price of HD Ready right now then go with Full HD. If you'll not be going for a new TV for a while and Full HD prices are comparable to HD Ready then go for Full HD now. All comes down to price and VFM actually.
Excellent! In line with what I was thinking too. Do not intend purchasing another TV in a year for sure.
Looks like, unless I get the Panasonic 42 PV8 at a real good price, a Full HD LCD will be a strong contender. Have an excellent AKAI CRT with stereo speakers. Very good brightness & colors. Plan to move that into the bedroom.
