Panasonic HTIB total system.
Option 4.. Save, scrimp , borrow, and beg until you have enough shekles to purchase a good system.....
I personally demo the Panasonic system (#2), very impressive, complete with multichannel power amp (quite powerful too), subwoofer (not bad at all), great integrated Blu-ray player (excellent picture), and wireless remote surround speakers (works extremely well). The total surround immersion and power of that system will blow you away. Oh, and bamboo speaker's drivers too.
Total score (from me), out of 10, I'll give it a 9.
* I never heard the Onkyo system, but I'll bet it will be as good if not better, but less the subwoofer and Blu-ray player, and the wireless surround speakers, and the bamboo drivers.
But an all THX system though.
So, all in all, that Panny system is hard to beat for a HTIB integrated system.
