About this time last year we put together a roundup of affordable mechanical keyboards aimed at gamers. We looked at a dozen popular options from brands such as Corsair, Logitech, Roccat, Tt eSports, and many others. The most economical keyboard featured in that roundup was $70. Since then we've seen and tested a few more mechanical keyboards, such as the Corsair K70 RGB Rapidfire, the Division Zero X40 and Das' Prime 13, all nice options, and all priced at well over $100.
So, what if you want a mechanical keyboard but only have $40 to spend? Not long ago that wouldn't have been an option, but with the market now flooded with loads of Cherry MX knock-off switches, this has enabled companies to develop very affordable mechanical keyboards.
One such case is the GranVela MechanicalEagle Z-77, available on Amazon for as little as $35 without backlighting and $40 with it. This is a fully mechanical keyboard using knock-off blue switches in a tenkeyless (87-key) layout.
