Tanga offers the refurbished Corsair Voyager Air 2 1TB Mobile Storage Drive, model no. CMFAIR-VA2-1000-NA, for $59.99 with free shipping. That's $15 under the lowest total price we could find for a new unit elsewhere. It features built-in 802.11n wireless and can stream media to up to five wireless devices at once.
A 90-day warranty applies, although it's unclear who backs it.
