VERY VERY YMMV: Polk MagniFi Mini Home Theater Sound Bar System $45
WARNING: YMMV like no other. YOUR MILEAGE MAY REALLY REALLY VARY.
I was watching the recent SD post about these for $135. I figured that since it was staying in stock at $135, I would watch to see if it would go any lower, and it did. $45 works for me. I wasn't greedy and only bought one of two. Good luck!
