Firstly, I don't know if I should put this here or the Computers, Software and Tech Support place. If it is in the wrong place, by all means move it.

I am wanting to get a new keyboard and mouse. I am using really crappy ones I got from work.
The two keyboards I was looking at are as follows:

-> Vengeance K95 Keyboard - http://www.scan.co.uk/products/corsa...2UUaAnka8P8HAQ

-> Razer Blackwidow Chroma Stealth - http://www.razerzone.com/gb-en/store...chroma-stealth

The two mice I was looking at are as follows:

-> ROCCAT Nyth Modular - http://www.amazon.co.uk/ROCCAT-Nyth-...ds=roccat+mice

-> Steel Series Rival 700 - https://steelseries.com/gaming-mice/rival-700

I am looking for a keyboard with macro keys and a mouse with extra side buttons. £150 max for keyboard and £75 max for mouse.
