Secondipity via eBay offers the factory-refurbished Marshall Kilburn Wireless Bluetooth Stereo Speaker, model no. 4091189, for $135 with free shipping. That's $24 below our January mention of a refurb and the lowest total price we've seen. (It's $105 less than the best deal we could find for a new unit.) It features a 3.5mm auxiliary jack, two 3/4" tweeters, a 4" woofer, and up to 20 hours of playback time per charge. A Marshall Kilburn warranty is included, but specific warranty details are unclear.
