ChubbiesTech via eBay offers the refurbished Harman Kardon Onyx Studio Bluetooth Speaker in Black for $59.99 with free shipping. That's tied with our February mention of a refurb as the lowest total price we've seen. (It's also $51 under the best price we could find for a factory-sealed one.) It features 60 watts of total system power, two 3" woofers, Bluetooth, and 60Hz to 20kHz frequency response.

A 30-day warranty applies, although it's not clear who backs it.
