Monster via eBay offers the refurbished Monster ClarityHD Precision Micro Bluetooth Speaker 100 in Black, model no. 129234-50, for $39.93 with free shipping. That's tied with our mention of a refurb from last week and $12 under the lowest total price we could find for a new unit elsewhere. It's compatible with most Bluetooth 2.0 devices, has a range of up to 33 feet, and features up to five hours of play time.
