Both of those choices are very nice TV's, but the Toshiba has 3 HDMI & 2 component inputs vs 2/1 on the Panasonic plus it also uses a 10-bit LCD panel which results in somwhat better color reproduction & to my eye at least the Toshiba also has deeper black-levels.
I'm not going to shop around for you, but a glance at CC's website shows both models on sale for $799 so with a 10% discount coupon (available on e-bay) you can get either one for $719 plus tax & at the same price I'd go for the Toshiba ... how much cheaper can you get the Panasonic for?
