Corsair’s K-series mechanical keyboards are some of your favorites for gaming, and for general use as well, and the
popular K70 is down to $90 today with brown switches, or $88 with linear reds, both the lowest prices of the year.
Update: The Brown model has sold out.
The Corsair K70's aluminum chassis lends the keyboard a premium feel, and its key-by-key customizable backlighting is just plain cool. If you don’t already know what kind of key switches you like, Lifehacker has a great explainer to help you understand the difference. This is the keyboard I use every day, and I absolutely love it.
