I generally have that same problem. Video is my curse normally as I tend to notice every flaw with the screen/picture. In this case it was a combination of both performance and price.
The Panny was an easy choice for the family room where standard DirecTV and DVD's would be the only sources. An HD screen would have been nice but almost overkill.
The Pio Elite RPTV has the best HD picture I have seen to date and I have yet to have it ISF calibrated (next month). True if the price hadn't come down so drastically I would have bought a plasma with a lesser screen, but that would have been a compromise on picture quality for footprint and price.
I liked the Denon receivers but felt I got equal to better performance at half the cost thanks to the Pio 1014/1015. A true find.
I was considering the Rockets or B&W 601s for speakers but after listening to them all felt that while they were in fact slightly better sounding in my mind they weren't $1000+ better. I felt 90% (95% with the as-f2 and as-r1 setup) performance for 1/3rd the cost was the best decision for my room -- and my marriage!
It was a hell of a lot of fun accumulating, setting up, calibrating, and cabling/wiring the rooms. I promised the wife I would keep everything at least 2 years before changing anything -- it was so much fun, I am crossing off the days already!
