I ordered a PT-47wx53 from Circuit City because I could't come close to their price anywhere else. After a so-so sales experience, I bought it anyway. Now they're jerking me around on when it'll be available. For the same price ($1,200), should I get a Sammy HCN473W or for $100 more a RCA D52W15? At this price point is there much difference? Is the Panny significantly better that I should wait and be jerked around more?
