Avoid membrane boards. I do a lot of typing. last year itself i've killed 3 of them. Buy a TVS Keyboard gold and be content with it. They come with Cherry blue keys. Clickity clack is there, but for 1.5k its the best you can get.

TVS Gold is a great choice but it's around ~1.4k now - if you don't want to spend that much opt for Logitech Wireless Keyboard K270 - it's around ~1k and feels really good while typing
