Abt Electronics offers the Nike + iPod Sensor, model no. MA368LL/D, for $16.99 with free shipping. That’s $2 under our January mention and the lowest total price we could find by $2. This wireless sensor helps monitor your workouts on an iPod nano with the Nike + iPod Sport Kit receiver, an iPod touch (second generation only), or an iPhone 3GS; your data then can be uploaded to nikeplus.com to help keep track of your performance.
