I am using cable for the HD signal.
65 inches....wow... I know that if your room is not large enough a 65 will be totally overkill and may give you a few headaches. In my bedroom, my viewing distance is about 14 feet and that is perfect for me, just the right size.
If you are looking at going that big you may want to look at an overhead projector. You would be VERY surprised with the pic quality. I have even heard people mention the pic nicer then HD plasma. Plus, if 65 inches is not enough for you, you can grow the screen.
I wish I could have waited longer, but I loved what I saw and the price was right.
