One of the most common post-TV-purchase complaints we've heard is from people who didn't go big enough. More than any other 'feature,' stepping up in TV screen size is the best use of your money.

We recommend a size of at least 43 inches for a bedroom TV and at least 55 inches for a living room or main TV - and 65 inches or larger is best. Screen size: Bigger is better in our book. It's also best to shop for a TV in the fall, when prices are lower. Most entry-level TVs have a good enough picture for most people, but TVs last a long time, so it might be worth spending more to get a better picture. Smaller screens are cheaper, well-known brands are more expensive and spending more money can also get you better image quality. Price: TVs range in price from $100 to more than $2,000.
