Through gotapex.com, I saw what appears to be a good deal on the Panasonic PT-53TW53. They have it for $1,299.99 with free shipping and a $100 gift card. I don't know anything about how this model compares to the WX series. Is this a newer or older series? What are the advantages/disadvantages to the TW series? Does this appear to be a good deal? Does anyone have this TV? Thank you.
