Summary: I got this spring 2010 for about $425. The HD picture is great. I have Time Warner cable on other TV's and for this TV I just have a COAX cable running directly into the TV (no cable box). Most of the channels look good. If you view from close - say 5 feet - the standard def channels are not great... but this is mounted to wall and I watch from bed (about 12 feet) so it serves me just fine. Somehow the signal passed to the TV does allow some HD stations.
Summary: I just got this set FREE with the purchase of some furniture at Ashley's furniture in Philadelphia. Easy to set up. Easy to use. Other then it being heavy because it's a plasma I'm happy with it all around. I have Comcast HD cable. The audio is pretty good as well. I just picked up a JVC set that I'm not crazy over the stock sound system but this set sounds good enough all by it's self.
Summary: I got this TV for myself in December 2009. It has been about six months now, so I thought a review might help someone else who is looking at this or similar TVs. I got it from my local Costco and paid $540.00, which was and still is pretty good for a 42" HDTV. The picture quality is absolutely awesome. I have an older, 2002, 1080i Toshiba 65" projection in the house which has provided some excellent viewing over the years.
