If you don't mind a recertified model, the Westinghouse LTV-46w1 is a killer deal at $869. I paid nearly double when I bought mine new.
I won't tell you what I paid for my Westinghouse LTV-46w1 when I bought it a little over a year ago, but I will tell you I love it. (I frequently refer to it as my "third child," much to Mrs. Cheapskate's chagrin.) I'll also tell you that you can now scoop one up for the extremely less-than-I-paid price of $869.
This is a 46-inch LCD with a built-in HD tuner, Clear QAM support, and output resolutions of up to 1080i. It pairs beautifully with my media-center PC, but I've also used it with a cable box and TiVo and it works just as well. Plus, it garnered an extremely impressive 9/10 rating from CNET readers.
Now for the caveats. The LTV-46w1 has only one HDMI input, the speakers bite, and the remote has terrible range. Also, this deal is for a recertified model, not a new one; make sure you read eCost's policy regarding returns and replacements. It does include a 90-day warranty.
Some folks will balk at the 1080i, insisting on a set that offers 1080p, but I'm here to tell you, I've never seen a trace of flicker or any other supposed 1080i shortcomings. The picture is freakin' beautiful.
Unless you spring for overnight shipping (which runs around $200--ouch!), you probably won't get this in time for the Super Bowl. But it should arrive in time for next week's installment of Lost, which, truth be told, is the reason I took the HDTV plunge. And I've never regretted it for a second.
