CowBoom offers the used, 1st-generation Apple iPad 64GB WiFi + 3G Tablet in Black, model no. MC497LL/A, for $179.99 with free shipping. That's $50 under the lowest total price we could find for a refurbished unit, although we saw another used one for a buck less last month. It measures 0.5" thick and weighs 1.5 lbs. and features an Apple A4 1GHz processor, 9.7" 1024x768 LCD touchscreen display, 802.11n wireless, Bluetooth 2.1 + EDR, accelerometer, compass, and up to 9 hours of battery life.
