Can someone here tell me the non-Costco model number for the Panasonic TC-55LE54, 55" LED set? Also any feedback on this model is appreciated. I am moving to a new home and need to upgrade from my current Panny 42" Plasma. I love the plasma display so if you think I'm going in the wrong direction with the LED let me know. My preference is to buy at Costco. Thanks!
