There are many different brands that are considered to be the best for LCD LED TV's. Sony, Samsung, and Vizio are all great brands to choose from.
In my opinion some of the best brands for LED TVs that are at least 55 inches are; Samsung UN55B7000 55-Inch 1080p 120 Hz LED HDTV and Samsung UN55B8000 55-Inch 1080p 240 Hz LED HDTV.
I think that the best television brand is probably the Sony Bravia. They make a good LED 3D television, with a good picture, but they are also more expensive than other brands.
I have found that the website http://reviews.cnet.com/best-led-TVs/ offers an informative, well rounded review of LED televisions. In addition, the reviews are done in accordance with the different name brands and styles.
There are multiple brands that create LED TV's. Some include Samsung, Philips, and Sharp. There are many other brands available, and they are available at http://www.ledtv.net/LED-TV-Manufacturers.html
You can find a good 19 inch led TV pretty much from any electronic retailer. You can find lower prices at stores like Wal-Mart; but for the best brand, you might want to try best buy retailers.
There does not appear to be many stores that specifically carry Sanyo LED televisions. The only online retailer was Walmart.com for around $1400 for a 55 screen LED. If you are willing to purchase a LED TV from a different manufacture you may be able to find better deals on other brands from Best Buy, Sams Club or Costco.
There is no best TV out of all the different brands. Many of the TVs have different features and qualities that other brands do not have. The safest thing to do before spending lots of money on a product is to search the consumer reports and read reviews on all the different makes and models.
The bestselling TVs from Best Buy are the Insignia - 32" Class LED, Insignia - 19" Class LED, Samsung - 32" Class LED and Samsung - 43" Class Plasma. The full range is displayed on their website.
There are several brands of LED TV sets that come set with HD. But I think it is up to the cable package that you sign up for in which determines what channels you can watch in HD.
Both brands are very trust worthy. Instead of basing your purchase off of brands, base it off of other factors such as price, video quality, or if it's 3D.
You can purchase a LED-LCD television at Best Buy in St. Louis. Depending on the size desired, they start at $199 for a 19" television. A 55" will run you $3200!
