Harman Audio via eBay offers the factory-refurbished Harman Kardon Go+Play Micro Speaker System for iPod, model no. HKGOPLAYMICBLKAM, for $99.99 with free shipping. That's tied with our expired February mention of a new unit and $61 under the lowest total price we could find for a new unit today. It features 60 watts of total system power, neodymium-driven Odyssey tweeters, Atlas woofer, RCA video output, and more. A 2-year Harman warranty applies. Deal expires May 11 at 5:55 pm ET.
