A4C offers the refurbished Apple AirPort Extreme 802.11ac Wireless Base Station, model no. ME918LL/A, for $119.95 with free shipping. That's pennies under our mention two days ago of a refurb and $73 below the lowest total price we could find for a new unit. It uses 802.11ac WiFi technology, which offers up to 40% faster transmissions than 802.11n. Deal expires August 4.
Note, a 90-day A4C warranty is provided.
Almost anyone can do this increasingly lucrative gig and work as few -- or as many hours -- as desired.
