Thanks for that link, Matthew. Looks like there's going to be a small spurt of TVs from various brands sporting that 37" 1920x1080 LCD panel. Must be a new panel coming out of some particular fab plant.
I ended up ordering the one I linked at the top of the page because it had some good bundle deals at the time (free DVD player for example), but then Best Buy completely fsked me on the order. Claimed they couldn't verify my credit card information, then couldn't transfer me to anyone who could actually help me straighten it out. After two days solid of trying to get them to resolve my problem on the phone, I instead hung up and resolved never to purchase from Best Buy again.
So, needing a TV and needing it "now"-ish, I went to Circuit City and picked up a 32 inch TV with a lower resolution (768 lines) for a lot less money. I'm more or less happy with the 32 inch unit for now, but if I feel like being adventurous later I'll see if I can buy one of the 1080-line TVs.
