some of these retailers take the component boards out and sell them to you separately. some retailers include the dvi boards but in case they don't, spend the $150 to $175 and have them install it for you.. DVI HD reception will get you the biggest "oh my god" factor. be careful, you will become an HD snob! digital reception just won't cut it.>>>>>>>>>>
Part of what he is talking about is that the commercial version has little boards that can be added/removed for different input signal types (another advantage over the consumer version).
I don't know if some sellers actually do this kind of stuff but here is my advice. Buy from a Panasonic authorized dealer. You can get just as good a price. The TH50PHD7UY comes with one component, one s-video, one PC VGA, one composite. You will need to buy the DVI input board if you need it. I bought one from buy.com for $110.
If your source is HDMI then you need an adapter to go to DVI plug(no big deal); my source uses the DVI plug.
Also, the component input comes with BNC plugs so you will probably need 3 RCA->BNC adapters if you plan to use the component input.
The PC input is standard VGA type plug.
Also, beware of spending ridiculous amounts of money on cables; a DVI or HDMI cable is digital. Spending $50 or $100 on one is absurd (like spending $100 on a Ethernet cable). You should be able to get good ones for 10-20$.
The component input that comes with the set (and I'm sure will be on your satellite receiver) gives an excellent picture. I did not add the DVI for that reason, just needed another hdef input. You should probably just hook up the components as a starting position and then think about adding the DVI/HDMI input.
I bought my set from G&G technologies in New Jersey. They were excellent with service and delivery. This is not a plug for them; just information. They are listed on Panasonic's site as a commercial plasma dealer. I think you said you were from the mid-west and I think there is another dealer out there. The price was $3600 last month from G&G. Their delivery charge was also very reasonable.

It sounds like you do not need the tuner as you will have a satellite receiver.
It is crazy to spend $5000 or $6000 for the consumer version of this panel (IMHO) or spend $3500 on the consumer 42”.
