Macmall offers the Apple 2TB Time Capsule, model no. MD032LL/A, for $169.99 with free shipping. That's $20 under our mention from last month and the lowest total price we've seen for a new one. (It's a current price low by $79.) Time Capsule is an 802.11n WiFi base station with a built-in hard drive. It's geared towards Apple laptops for use with Time Machine.

Note that this isn't the latest version, which is now called Apple Airport Time Capsule.
