Recommandation for mouse and keyboard

[Tanoxil]

Hi, I have about 100$ Canadian to spend on a mouse and a keyboard. It will be mainly used for gaming. What would you recommend?

What do you think of this keyboard: https://www.amazon.ca/Redragon-KUMARA-Backlit-Mechanical-Keyboard/dp/B016MAK38U/ref=sr_1_3?ie=UTF8&qid=1515558599&sr=8-3&keywords=mechanical+keyboard
Will I see a big difference between membrane switches of the corsair and the mechanical switches of the red dragon?
