@Melonlity -- I think Terrificli has a point. Why spend money for a "sound bar" when you can shell out a few bucks and make your perfectly good surround sound speakers wireless and, therefore, more convenient? Remember, we're talking about saving money here and not going out and getting more stuff.
Also, some people like "real" surround sound better than what is available from those sound bars you mentioned. There is simply no substitute for a couple of satellite speakers mounted behind you and making all kinds of racket during a movie. You won't get that with anything but a traditional set of surround sound speakers.
