Why are you getting a commercial model if you want all the features of the consumer model? You'll end up paying more because a decent atsc tuner is about $300, a stand is about $200-300, matching Panny speakers are another $300 (unless you really want ugly cheap speakers next to your new plasma) and the cable to the atsc tuner is another $50. Then when it's all together, it's not integrated, you'll have an external receiver box, the remotes will be seperate and you'll have extra wires for power, video and audio to contend with.
Don't get me wrong, I have a 7UY and I did it because I don't use the stand or atsc tuner (I have sat tv) or speakers (I use my HT) but in your case, it's just not worth it.
