Good Guys Electronics offers the refurbished Unlocked Asus PadFone X 16GB Android Smartphone for $79.99 with free shipping. That's the lowest total price we could find by $15 for a refurbished unit. It features a 5" 1920x1080 touchscreen, Qualcomm Snapdragon 800 2.3GHz processor, 2GB RAM, 16GB storage, 2-megapixel front-facing camera, 13-megapixel rear-facing camera, MicroSD slot, and Android 4.4 OS (KitKat).
Note: A tablet dock is not included. A 90-day warranty applies, but it's unclear who offers it.
