This new unit is much better than what I have. Mine is an old model that is replaced by this model. This new model has 2 more S-video inputs, 2 more component inputs, built-in NTSC, closed caption, scalable P-I-P, brighter ratio, over billion colors, alarm clock, DVI port, and speakers. Mine has none of the mentioned. On top of that, the retail on this new unit is $500 less than the old unit. What a deal! I wished that I had waited. The only thing about this unit is that it does not accept 720i signal. ABC network broadcast some programs in 720i mode. You can use standard satellite decoder box to scale down to 480i, or up to 1080i if it's a HD decoder. The new unit accepts either resolution.
For a better deal, check out www.justsayelectronic.com., which is a Deal Time Certified Dealer. From the Panasonic HDTV discussion, a very knowledgeable person on such web site has bought a Sony TV from them. Justsayelectronic.com listed the new Pana unit for $3200 + $200 S&H. The $200 S&H sounds seems like a standard fee of White Gloves. Call them to verify.

As far as cable, I am not familiar with DVI cable. All my video cables are from IXOS (England). Not your best, but better than Monster Cable in terms of price for similar performance, if not better.
