I just purchased a Mitsu WS 55809...very impressive at the store (I have not received the set yet). Couple of questions: 1. The set is HD-Upgradeable so how is it that I upgrade to HDTV? Is it through a digital cable box or do I need to buy a specific component to convert the set to HD? 2. Is it worth upgradeing now or should I wait for prices to drop? I will not use the set until December of this year being that this is when my house will be ready to move in. The reason why I purchased this set so early is beacuse the store where purchased made me "an offer I couldn't refuse." Any comments on the WS 55809 would be greatly appreciated. Thanks for the help!
