MacMall has the previous generation (Apple just announced the newest model) of the Apple Time Capsule line. The 2TB Time Capsule that was until few days ago $299 is now $170. If you're wanting a larger model, the 3TB version is selling for $229 (regularly $399).
This is a great deal if you have an Apple computer. Back up your computer in the background and never worry about losing your data again. The Time Capsule also doubles as a wi-fi base station.
