I found the Insignia 39″ 1080 120Hz LED HDTV to be a reasonable buy mainly due to its low price tag. The picture & sound quality are not top notch by any means, but if your on a budget you will not find another similarly sized LED HDTV with a 1080P 120Hz screen in the same price range. For the average consumer, this HDTV will probably satisfy your needs, but if your picky about your audio and video quality or have more money to spend then your better off moving on to bigger and better models.
Overall, I found the Samsung UN40ES6150F 40″ LED HDTV to be an impressive TV at a reasonable price. It features an beautiful design, excellent picture, great sound quality, lots of inputs, and Smart TV capabilities. If you can get over the slow performance of the Smart TV interface and are not planning on relying heavily on this TV's web browser feature then you will not be disappointed with its performance. The Samsung UN40ES6150F 40″ LED HDTV is on the same level as some TVs that are double the price and for that I highly recommend this TV to prospective buyers as I believe you are getting a large amount of value on the price you are paying for the product.
Overall, if your in the market for a 46″ TV and desire both Wi-Fi capabilities and 3D technology then this is a solid buy. It is a bit on the expensive side especially considering that there are no 3D glasses included, but I think the plethora of features warrant worth the price and will make it a relevant TV for years to come.
If you are on a budget and looking for a new LED HDTV with a screen larger than 40″ then you will want to invest into the Samsung UN46EH6000 LED HDTV. If you are looking to spend more money and want the additional features of other competitors such as Wi-Fi connectivity and web surfing then you will likely want to look at more expensive models.
