All you people I've been interacting with in person, congratulations! You no longer have to endure my obsession with making sure I pick exactly the right TV and get it at a good price anymore. I ordered the Samsung LNT-4081F from Crutchfield (via Amazon.com) for $1199 (free shipping). I also got a new TV Stand from Amazon shipped faster than the TV itself, so I should be able to set up for it in advance.
I'll still need some kind of shelving unit to hold the components that don't fit on the TV stand; I'm hoping those will go nicely out of the way in the corner and give the living room a LOT more space.
Now to figure out how long I can hold out before getting some HD sources. And replacing the amp. And... And...
Oh my, I've just cracked open the money spigot, haven't I? Bleah.
