Shopping for a TV these days sure isn’t what it used to be. In the old days, all you had to do was find out how big your next-door neighbor’s TV was, then go to Sears and buy one a few inches bigger. Now, with HDTV technology exploding in every direction, you need a deeper understanding of the options available before you decide what to get. It doesn’t need to be intimidating, though, if you break the decision process down into a few steps.
