Size Name: 40-Inch
After researching Bravia TVs, I decided to go ahead with this one since it is one of the newer releases for 2011. I'm glad I waited, as this TV is clearer and more vivid than those of some older models or rival brands. Picture quality is clear with no fog or motion blur. PS3 games and Netflix look absolutely amazing. The only thing this TV needs now is a sound system to broaden the audio experience. If you're having sound issues, try messing around with the 'steady sound' and 'clear voice' options to even things out and make them less muddy.

In stores you may see this TV's picture slightly less bright than others, but that is because of the built in light sensor that's located on the front of the frame. The picture automatically adjusts to best fit it's surroundings, and that's what's truly great. No fussing with brightness settings all the time.

Overall, worth every penny. Stick with Sony and you won't be disappointed.

The SONY KBL32BX450 with high definition 1080p is an entry level model with outstanding picture quality. This is a highly recommended HDTV for you.

I had researched purchasing HDTV for the bedroom and the SONY is better than the rest (LG, SAMSUNG, PANASONIC and budget models). You pay more for the SONY but you getting a SONY. It is worth the difference. Do not compromise.

This is a new 2011 model with basic features. There is no Wifi, this is 60Hz and is not an LED TV (however picture quality compares to LED sets). There are only two HDMI ports that may not be enough for some people. The only "complaint" is the sound quality. You will need to adjust the bass/treble and use the equalizer in Custom Mode. It is the same issue that flat screen sets just don't have great speakers. Regardless, this is an excellent television.

There are enough settings with options to calibrate and customize the picture to your liking. It is best to disable the ambient light sensor that restricts the brightness and vivid contrast of the picture. Once calibrated, the picture is awesome. The fleshtones are realistic. There is abundant contrast with the blacks are coal black and whites are bright white. The colors are vivid and vibrant. The set will require picture adjustment and calibration out of the box. Motion blur is almost non-existant for a 60Hz set.

The features and specs of this set are well documented. You have a USB port to view pictures and videos.

If you are very budget conscience then consider the SONY 720p model KDL32BX320. This is also a great set but you don't pay for the Full HD. If you won't do gaming or watch BluRay then this may be for you. If you are looking to install in your living room then look for a SONY with a larger screen.

I purchased this from a store with special grand opening sale but wanted to post review for Amazon folks. I would typically buy from Amazon.

Size Name: 46-Inch
For those seeing the 1 or 2 star reviews, do yourself a favor and ignore them as they address aspects of the TV that are common knowledge to anyone who has done their research and are flaws present when shopping for ANY TV of this type.
This is doubly true for the speakers - if you're expecting a massive wall of sound from any TV's internal speakers then it's a wonder you were intelligent enough to type a review on Amazon.

Now, on the the important stuff.

From a presentation standpoint, the TV is understated and classy. The glossy black bezel is attractive in it's simplicity, with the only deviation of color being a thin strip (about 1cm) of dark gray at the bottom of the TV. The gray strip house the sensor bar and small power leds.

This is a 'budget' TV, and with that classification aside, the image quality on this TV is amazing. After some careful calibration, the picture shows deep, dark blacks, vivid color, sharply honed detail, and extremely smooth motion.
Despite having a lower refresh rate than higher-end sets, this TV gives fluid, artifact free motion - even in action scenes with lots of quick camera cuts.
The image quality is on-par with much more expensive sets, and given the actual price of this set, the image quality alone makes this TV worth a buy.

However, there are caveats and they present themselves most notably in the inputs - or should I say, the lack thereof.

It's with the inputs where you realize where Sony skimped in order to deliver a set of this size at this price.
You get 2 HDMI, 1 Component, 1 Composite, 1 Coaxial, Analog and Digital Audio inputs, a VGA, and a USB input.
This input scenario posed problems for me, as I have far more devices than this TV can accommodate on it's own.

This Sony LCD is one of the best deals anyone is going to get. Like the other guy mentioned, I purchased mine directly from WalMart for $588! The image quality is outstanding. I have made a few tweaks like lowering the brightness, to help achieve deeper blacks. I will use a image calibrator later. The screen does have a slight glow at the top corners, but that is only visible during extremely rare black-out scenes. I noticed it while loading Blu-Rays, but once the movie starts the screen is very vibrant! The sound quality is not all that refined. I don't have money for an Audio system or receiver so I will just have to fiddle with the settings like bass and treble till I find the optimum tune. There are plenty of A/V connections, a plethora of options in the menue to fool around with, and a great remote. I have a PlayStation 3 hooked up by HDMI cable. That allows the system remotes to control devices, very cool! Go buy one!!!
