Monster via eBay offers its factory-refurbished Monster ClarityHD Precision Micro Bluetooth Speaker in Black, model no. MBL MBL CLY MBT 100 WW, for $29.50 with free shipping. That's tied with our refurb mention from three weeks ago as the lowest total price we've seen for this speaker. (It's also $31 under the best price we could find for a new one.) It features hands-free calling and range of up to 33 feet.
