Microsoft Natural Ergonomic Keyboard 4000

Although you can spend much more on an ergonomic keyboard, the Microsoft Natural Ergonomic Keyboard 4000 is easier to use than most, with a familiar layout that's tweaked to decrease hand and wrist stress. The unique curve of the keyboard encourages users to hold their hands in a more comfortable and ergonomically correct position, and the traditional key layout helps minimize the learning curve. It's also hailed as a bargain, something unusual in keyboard reviews, which typically complain about the high price of top-performing models. In addition to the ergonomic design, the 4000 also includes useful convenience features, such as a zoom option.

Scott Clark of EverythingUSB offers the best review of the Natural Ergonomic Keyboard 4000. MaximumPC's review is abrupt but covers most major aspects of the keyboard. Lastly, PC Magazine's Joel Durham includes the Natural Ergonomic Keyboard 4000 in his best-bang-for-your-buck article, recommending the 4000 as the best, reasonably priced keyboard.
