I got the panasonic viera tx-p42c10y (1280x720 resolution), bought it when it was new (2008-2009 something) and without doubt the best flatscreen TV I have had, super responsive and really nice and clean picture.
I still use it even if I have other TV's today (it's really responsive and has really low input delay), but funny enough I do not even to this day have any burn-in issues, not a trace of anything and I have had a HTPC on it since it was new and multiple times forgot it on with static images from forums and games etc via both the HTPC and consoles but the shadow image dissaperes after a few hours so no permanent damage, so it's a kickas plasma display.
