ChubbiesTech via eBay offers the refurbished Harman Kardon Onyx Bluetooth Speaker for $59.99 with free shipping. That's $35 below our mention of a new unit from a month ago and $52 under the lowest total price we could find for a new one today. It features 60 watts of total system power, two 3" woofers, Bluetooth 3.0, and a 60Hz to 20kHz frequency response.
A 30-day warranty applies, but it's unclear who backs it. Also, this refurbished unit may have light scuffs and scratches.
