I am looking to purchase an HDTV but when i went to comcast's website it says you need a HD-ready TV with a built in tuner. I thought ok no problem, well when i search for HD-ready tv's it says that those do not have a tuner built in, so my question is do i need to purchase TV with the built in tuner or not? The ones with the tuner built in are more expensive and harder to find . does anyone know wher i can find one around 34' and under $2000. I would call comcast and ask them al this but getting an answer from them on anything is always impossibe.
