Audio is a critical component of any home theater, but if you don't have the money or space for a complete surround sound system, a sound bar is a great alternative. Ebay has a fine deal today on a manufacturer refurbished 40" Vizio unit, including an all-important wireless subwoofer. At $140, it'll save you about $40 versus buying new. The unit won't deliver theater-quality audio, but it should be more than sufficient for non-audiophiles. [eBay]
