I treated this tv as if I was buying a house. I made a Checklist and I made sure the TV contained it.

My List was as follows

550$ Budget --- Check!
(bad economy)

HDMI ports 3+ --- Check!

120Hz Refresh rate --- Check!

100,000:1 or over --- Check!
Contrast ratio

37"+ and Full 1080p --- Check!

Response time 3ms~ --- Not Check!

(5ms is usually the standard
for non-plasma displays)

YCrCB, USB 2.0, RGB --- Check!
inputs

Notice-
Contrast ratios are not very standardized and should not be a
major influence when buying your television! You can check this
yourself by going down a local TV retail. If you notice the contrast
ratios will vary widely from TV to TV and yet the image will look the same.
This is due to the fact that TVs with lower contrast ratios can use
visual tricks that make pictures appear much livelier or bright... Read more

First off, delivery was fast and the TV came in undamaged. Normally, I'm fearful of any type of shipping short of white glove for big ticket items like TVs, but FedEx didn't disappoint.

The TV itself is nice. The picture is satisfactory, and there are a good number of options for tweaking picture. I found a nice mix myself. For the ~500 that I paid for it, I'm satisfied with the picture. There isn't anything to complain about the sound. While it's definitely not top of the line audio, there's no outright problems, and the sound is loud enough to fill a room. After you get to about 70 in volume, there's a slight buzz from the speakers, not noticeable unless you're less than a feet from them. For standard digital television, there is sometimes a slight lag between sound and picture. When there is, its very noticeable and throws the experience off. But even this can be solved. You can mess around with the audio and picture settings to sync them.

I've been researching TVs for a while and this is the ONLY TV in my price range that had my select list of features -- most notably 120hz refresh rate with a way to adjust the dejudder (Vizio's smooth motion feature). TV was set up in 30 mins, and most of that was me coordinating other component cables. Picture is epic. Sound is good. Only issues so far: 24hrs of Picture Jumping that went away on its own accord, and the sound feature that is supposed to even out the different sound feeds doesn't work too well. Commercial sound versus TV program sound. And sometimes I think the sounds goes up and down, but I haven't fully explored this yet. I'm going to hook up surround anyway. This TV was a great hybrid of quality, features and price. Highly recommend. (This 2011 TV replaces the 2010 E420VA.)
