A decent (not great, not junk, but decent) current plasma should have AT LEAST a 30,000 hour half life; most have 40K hour half lives; many have 50k or 60k half lives (like the Panny). The key is for the first 100-200 hours: turn the contrast and brightness WAAAAY down low, fill the WHOLE screen with non-static images (no network bugs, no black bars, no top or bottom news tickers), and just run the TV. You can even run it while you are out or at work. This is done to 'condition' the phosphors in the panel. The reason plasmas can look dull and washed out after a few years is due to the first few hundred hours having the C and B settings way too high; keep them low early on and it'll add years to your plasma's life. There's a lot written about it over at AVSforum.com; check out the LCD/flat-panel forum. There's even a DVD/CDr 'conditioning' disc tha you can download and burn that just fills the screen with one color at a time for like three seconds each; it runs on a loop, so you just hit play and let it fly....
