Before you head over to the electronics store and come home with a giant TV, you have to know what you want. You have to know what size you want, what features you want and what brand you want.

Let's take a look at the top three big screen TVs to buy for your home.

First, decide what room you want your TV in. If the room is too small, the TV will not look good in the room and it may even hurt your eyes. If you have a nice-sized room with a nice corner, put your TV in the corner and angle your couch towards it. This will create a perfect viewing angle.

Next, decide the brand name you want. It used to be taboo to buy one of the off-name brands like Sanyo or Westinghouse. Now, technology has pretty much leveled off and even Chinese no-name brands like Hisense and TCL will still get the job done.

Finally, decide your price point. Do not overpay, but certainly do not underpay. Read the reviews before making a purchase. Do not let the salesman convince you until you have read reviews and had time to test the TV out.

Here are three good choices that are 42 inches or larger.
