I want to buy a new LED LCD TV with some type of Guide Plus or TV Guide installed. I have had this feature before and I really like it.

Are you looking to connect basic cable or antenna? Almost all TVs will provide information for antenna as this information is sent with the new digital signal (assuming you're in the US).

If you're looking at connecting cable then you should get an HD cable box (which has the guide built in) if you're looking to get an HDTV, otherwise at best you will probably only get your local channels in HD. If you connect basic cable, I don't think hardly any TVs will come with much of a guide for you.
