Not alot of online reviews other than the QVC reviews. JVC is a good reliable brand according to consumer reports.
The only 40" LED 1080p, 120 Hz I've found at a better price is a Westinghouse on Amazon.
Despite the Westinghouse's positive reviews on Amazon other than difficulty mounting, consumer reports states Westinghouse as the brand with one of the highest failure rates.
Also Amazon has a Vizio with similar specs and its a smart TV for $499.
New Egg as this tv for $550
Whereas this woot deal isnt a huge price break, this is a very good tv for the cheapest you'll find it new online at this point.
