Cheapest I've ever seen one of these, it is a current model going by the new tramp stamp style logo and is around £50 cheaper than most other sellers. This is a top end mechanical board, only really bettered by the Corsair RGB models however the K95 RGB is around £150.
The Corsair Gaming K95 is a fully mechanical, backlit keyboard with 18 dedicated macro keys for exceptional gaming performance. The built-in Cherry MX Red switches deliver smooth, linear response for ultra fast double and triple taps without the audible click. Every key is individually lit for brilliant backlighting and easy customizability to highlight important functions. The black anodized brushed aluminum structure provides rugged durability and a professional-grade finish. 18 dedicated macro keys with three banks give you easy, single keystroke access to up to 54 of your favorite presets and key combos. Plus the 122Key Roll-over on USB and 100% Anti-Ghosting mean that every key you touch translates directly into the game.
