I am having a hard time deciding which Tv to get, the TH-58PZ800U or the PN58B550. My budget is around 2000 and Ive been doing a lot of research. I wasnt able to view the Panny in the store as all the places around me dont have them up for display. Is there a better one out of the two? Are there newer models that are in the same price range that are better? Please help as I think I am overthinking this.
