I really love the layout of the second generation ergonomic keyboards from Microsoft, but they don't sell them any more. The plain white and black keyboards are the best, but even harder to find. This is a good alternative; the layout is the same and there are a lot of nice extra functions available in the multimedia buttons along the top.
If you need an ergonomic keyboard but can't spend a hundred dollars -- or more! -- then snap one of these up before they're all gone.
