I also have one. The PQ puts my local theaters to shame. Every guest so far has agreed. In fact, they are more convinced of their opinion than I am of mine. Its nothing short of glorious. Sorry, please excuse my heavily biased subjective blather, because it's even better than expected, and I was expecting a lot.
I was going to get that Pana later this year. Some liken it to the poor man's RS-1. Then I ran in to RS-1 open-box fire sale at AVS. They sold out in one day.
Got it for 3k (just a few hundred more than the local Costco/Pana price), replete with 2 yr warranty, only 3 hours on it. Pulled the trigger very prematurely, but Im sure glad I did. If you are a bargain-hunter, I would bookmark the Digital Hi-end PJ subforum, and check in daily as a ritual. That firesale was not the first, and it won't be the last.
There is an interesting tweak thread that supposedly gets the RS-1 to the performance level of an RS-2!
Not for me though... Id be too scared, and also, I am way more than satisfied. However, this is my first PJ, and I hardly qualify as a real videophile. Im a movie-phile.

So... for your puchasing conundrum. Its impossible to say what to do. Some buy Kuro's, others get a Panny. Some get DLPs, others get XBR-2 sxrd. Value is always subjective.
