Buy.com has the refurbished Apple Time Capsule 500GB Wireless Hard Drive for $139.99, $20.00 off their previous price. This drive is Mac and PC compatible, and shipping is Free. It's a great deal, and you will be able to:

• Connect your DSL or cable modem to Time Capsule and quickly create a new wireless network — or extend an existing AirPort-based network — using the easy-to-use AirPort Utility for Mac and PC.
• Time Capsule uses next-generation 802.11n wireless technology to deliver up to five times the performance and up to twice the range of 802.11g wireless networks.
• It also works great as a wireless hard drive whether you have a Mac or PC. It sets up in a snap, giving you a networked hard drive you can use for storing and sharing any kinds of files.
• Print documents, photos, and more from any room in the home or office to a central printer connected to Time Capsule via USB.
• Protect yourself with the built-in firewall and industry-standard encryption technologies including WPA/WPA2 and 128-bit WEP.
• It works flawlessly with Apple TV, iPhone, iPod touch, and all your other Wi-Fi devices that use the 802.11a/b/g and 802.11n draft 2.0 wireless standards.
