I have installed 2 Vizio 2.0 sound bars, one 29" and one 38". Both sound very good and are superior to several more expensive sound bars that I bought and returned because they sounded weak. The 29 is actually on a cart that we use for outdoor movies at my university and it is plenty loud. The speakers also have Bluetooth so you can play music from your phone or tablet too.
Long story short, I would recommend the $100 sound bar. It's easy to install, has a wide frequency response, and produces lots of clear, distortion-free sound.
