I've been limping along with an 7 year old 42" NEC XR4A plasma for too long. Image is dimming and think the power supply is about to go. Been a great display...

Want to jump to an LED in the 48" range (samsung 48h6350) as my 42" is slightly undersized for our cabinet but cant go any wider than 42.5 inches but I'm afraid of motion artifacts as i'm kind of a video nut.

any opinions would be appreciated...
