Get an 2TB Apple Time Capsule Back-up Drive and WiFi Router for $169 plus free shipping at B&H Photo. This was the lowest price by $30. It's a full-featured 802.11n WiFi base station that has four Ethernet ports for wired devices and a USB port for printer sharing. Editor's note: I use this drive and it is one of the most reliable and easy to set-up back-up drives I have ever purchased. It's also extremely quiet and a great WiFi router. There is no sales tax (except in NY).
