is it time to change the tv?

We are being bombarded with advertisements these days.... mostly from electronic stores in the paper and in inserts as well. I've got tired of looking at the ads now, but it has put a seed in that it's got me thinking that maybe it's time to upgrade our current TV to something like a Samsung HDTV or some such thing. Very frankly, shopping for stuff like this confuses me, so I put it off or put the decision on someone else's shoulders. Our current one is just over two years old, so it really doesn't need replacing, but if one gets a great deal, then maybe it's worth it. Let's see!
