Anything I've ever bought by Sony, has outlasted anything I've ever bought by Panasonic.........
period.
And for true buying nirvana, avoid JVC and Sharp like the plague.
Anyhoo, I usually buy any major purchases on Black Friday, at Best Buy.
Last year, it was a BB house brand, "Insignia" 46" LED @ $329.95. Took it home, plugged it in, it works fine. At that price, it's a throwaway anyway. "Funai" electronics used to make their "Dynex" brand. I haven't bothered to Google the UL lab number on this turkey to find out where it came from.. Most likely, because I don't really care.
You do realize the 35 mm feature films run @ 24 frames per second, don't you? 480i TV runs @ 29.97 FPS but, that's an interlaced scan, so it only puts 15 FPS of actual information.
That kinda negates the need for anything faster than 60 Hz refresh. At least it does for me. The G to G time on the panel is likely a reason for any noticeable lab, or at least as much as the refresh rate.
Here's a tip, Best Buy always sells printer /scanner / copier combos at below cost on Black Friday. You can throw last year's printer away, and just buy a new one. After all, re-inking the current printer, would cost more than replacing it.
