Blutek via eBay offers the refurbished Aliph Jawbone JAMBOX Wireless Bluetooth Speaker in six colors (Red Dot pictured) for $59.99 with free shipping. (A4C has it in White only for just pennies less.) That's $3 under last month's refurb mention and the lowest total price we could find for a refurb by $10. It features up to a 33-foot range, up to 15 hours of battery life, and speakerphone capabilities.
Of note, no warranty information is provided.
