Help, I had a sizeable store credit from Sam's Club and I went in to buy a Vizio SV470XVT. A Direct TV salesman was set up there and saw me loading the Vizio on a cart. He convinced my wife ( and me reluctantly) that the Philips 47PFL7403D was a better buy. $100 less. I knew I wanted 1080 with 120Mhz, which both have. But he blindsided me with contrast ratio comparisons. Vizio 6500:1 vs Philips 29000:1. I bought the Philips last week, but have not opened it, as I'm not sure if I made the right decision. I would appreciate any and all input as to a comparison of these two TV's. My wife is hounding me to set it up!
