Anyone who can advise me on a sound bar for my TV?

2

I have a 42" LG television with which I generally satisfied except for the sound quality. I’m considering adding a sound bar, but I have no clue how to judge one. Woot has a 38" refurb Vizio for $$90 (http://www.woot.com/offers/vizio-38-2-1-soundbar-w-wireless-subwoofer-25?ref=w_cnt_wp_0_1). More info on Amazon is here: https://www.amazon.com/VIZIO-SB3821-C6-38-Inch-Wireless-Subwoofer/dp/B00SMBG8QY/ref=sr_1_1?ie=UTF8&qid=1490946113&sr=8-1&keywords=Vizio+SB3821-C6C.

The Spouse is pretty good at installing stuff, so that’s not a worry. I just need some help in figuring out if Woot is a good bargain for this. (Does it help to know I watch it from about 10’ away?)

I have to make the purchase before midnight ET Friday. Thanks for any info.
