in case people were wondering what i ended up with: after much research and exchanges on forums (
http://www.avsforum.com/avs-vb/ is a pretty good one), i decided on the Samsung LN46C630 (46" LCD, matte panel, 120 Hz, 4 ms, 80,000:1, blah blah blah). folks who aren't putting the set in an overly-lit room should consider the LNxxC650 series - it has the glass "Ultra Clear Panel" which improves contrast (and color according to some), at the expense of potentially more reflection. then again, you should also consider plasma at that point.
samsung appears to be getting out of the LCD game: despite improved specs over last year's model (the B630), the new C models are cheaper. i got mine for $890 ($989 with $99 cash back from bing.com).
right then, off to find a bluray player so i can watch those gorgeous discovery channel nature specials...
