BuyDig offers the factory-refurbished Motorola HZ720 Elite Flip Bluetooth Headset, model no. 89504n, for $19 with free shipping. That's a buck under our March mention of a refurb and the lowest total price we've seen for this headset. (It's also $10 less than the best price we could find for a new unit today.) It features an in-ear hook, flip design, extended range of up to 300 feet, and up to six hours of talk time. A 1-year Motorola warranty applies.
