I just received a postcard from Mitsubishi electronics. On the postcard, Mits has a "Promise Module" which will upgrade my television to fully integrated HD performance. The price listed on the card is $995 installed (plus tax and shipping). Does anyone know anything about this? Is this set-up better than an HD set-top box? Is the $1000 price tag worthwhile? I'd love to have your thoughts on this. Thanks in advance.
