Best budget mechanical keyboard?

[NirK]

I want to use it for FPS gaming such as CS:GO as well as general usage. I do not want one that makes loud noises and I would like a numpad, the only functions I use on my current keyboard are volume control and sleep button, although maybe this can be mapped to a function key if the keyboard does not have dedicated media buttons?

Price limit is £70. Please tell me which is the best.

Ok thanks for the replies....

So does a mechanical keyboard actually make any difference to gaming? Will it actually make me play any better than my dome keyboard? Because CS:GO uses a lot of strafing and stopping I was thinking it should help, but my friend says it makes no difference at all...

Also can the Steelseries 6Gv2 do volume control and sleep?
