I have this box hooked up to my Panasonic EDTV 42" and am very happy.
1. It only cost $475 at Best Buy.
2. It has a very user friendly, fast interface.
3. It will scale SDTV up to 1080i and present it in a wide variety of formats (cropped/zoomed, sideboxes, etc).
4. It is very reliable. It has never not worked.
5. It has a good remote that will control my receiver.
I highly recommend this box. You are going to love HDnet.
