Northwest Outdoor via eBay offers the refurbished Garmin Forerunner 225 GPS Running Watch, model no. 010-01472-10, for $114.99 with free shipping. That's $24 below our mention of a new unit from two weeks ago and the lowest total price we've seen. (It's also $15 under the best deal for a new unit today.) It features Garmin Connect, wrist-based heart rate monitor, GPS-enabled, and activity tracking.
Note: A 1-year warranty is included, although it's unclear who backs it.
