Amazon offers the Western Digital 2TB My Book Live Personal Cloud Storage Gigabit Ethernet External Network Hard Drive in Black, model no. WDBACG0020HCH-NESN, for $99 with free shipping. (Fry's Electronics charges the same for in-store pickup only.) That's $0.05/GB, $41 under our October mention, and the lowest total price we've seen for this NAS. (It's a current price low by $60.) Sales tax is added where applicable. It's compatible with Apple Time Machine and features a built-in media server for streaming to any DLNA-certified device, automatic backup, and more.

Update: Amazon has since increased in price; however, Fry's Electronics still offers it for $99 with free in-store pickup.
