The format wars are finally over so maybe it's time to upgrade the movie portion of your home theater. Many deal watchers expect Blu-Ray disc players to be one of the most popular gifts of the season because the discounts are so deep compared to previous years. As recently as six months ago the cheapest model would have set you back $400. (In fact, Sony's Playstation 3 used to be the most inexpensive BluRay Player available.) Today, the prices are more in line with a high-end DVD player. But don't worry about those old DVDs sitting around. You can still watch them on the Blu-Ray Players, just not in high def.
