I am looking at the 65" Panasonic TC-65PS14. It is at sale at Costco for 1999. I would like to know what the difference is between this TV and the TC-65PS1. I was looking at the S1 at best buy and really liked it. Now i am shopping around for the best price and i stumbled across the S14. They are both 1080p but is the quality better on the S1? Do they both have the same features? An answer would be greatly appreciated!
