Think it's finally time to upgrade my viewing experience. You'd laugh if I told you what I am currently using. Anyhow, want to get a hd tv even though I don't yet subscribe to hd. The tv I'm thinking of getting is Panasonic 42in plasma with 720p, currently on sale for $599. This is in my price range and seems a good deal to me. The 1080p plasmas are out my price range, so I would like to know if the difference is substantial. Also, the lcd tvs with 1080p are in this price range, so would I be better off getting the higher pixels?
