After quite a while of mulling over a plasma purchase, my brother finally got one. I gave it my approval.
Panasonic TH-C50FD18. 50", 1080p, supposedly the same as the 80u series, except with addition of PC input. Looks great.
$1,199 at Costco, 2 left after the purchase, and standard is the 90 day return policy, no questions asked, and extended 2 yr warranty, for free of course. If anything happens to the tv, you basically get to trade in for full credit. I know, pretty insane CS.
Brother was a bit disappointed that the component connections from Xbox don't work on the new TV! He now needs to buy a $50 hdmi adapter for it. I'm guessing stoopid HDCP crap.
