B&H Photo-Video offers the Apple 2TB Time Capsule, model no. MD032LL/A, for $179.99 with free shipping. That's the lowest total in-stock price we could find by $49, although we saw it for $11 less in June. 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 these aren't the latest versions, which are now called Apple Airport Time Capsule.
