Driven GPS via eBay offers the factory-refurbished Garmin Forerunner 210 GPS-Enabled Sports Watch with Heart Rate Monitor in Black, model no. 010-00863-30, for $79.95 with free shipping. That's $6 under the lowest total price we could find for a new watch, although we saw a refurb for $5 less last spring. It features an automatic time zone, up to eight hours of battery life in training mode, ANT+ compatibility, position, speed/pace, and distance and calorie data. A 1-year Garmin warranty applies.
