If money is a non issue.
The Pioneer Elites are the ABSOLUTE BEST.
I have a samsung 51 plasma in the bedroom... it's good, but not near the pioneer that my MIL has in her bedroom.
THen we have the 61 inch DLP Samsung in the living room... and its picture full on front is better or as good as the plasma..
But if money is a non issue.. Pioneer Elite or Sony XBR is the way to go.
Both are AMAZING while Samsung is just good.
ANd if you want to buy American.. get a Vizio from COSTCO not from WalMart.
