I bought one of these, also Factory Reconditioned, from woot for $520 last November (hey, woot, any chance of a compensation…? eh…? eh…?). The sound is phenomenal. The sub and soundbar blend together perfectly and the spectrum is incredibly full.
I just wish it had ARC for the output line going to the TV. With SmartTVs having apps contained to the TV OS, you have to run an optical out cable (or 3.5mm, I guess) to the sound bar from the TV, and then set the sound bar on the optical input.
