CM Storm Quickfire
One of the cheaper options on the market - you can buy for around $60 if you look in the right places. There is no backlit option but there are a lot of versions available. It is a full size mechanical gaming keyboard, doesn't come in white but is available in black.
Logitech G710 Plus
Looks fantastic and is Logitechs main keyboard - if you are a serious gamer you want to check out this gear. Personally, it is part of my arsenal.
Again, available in a tonne of different configurations this gaming keyboard is available in black. At the time of writing this is one of the most popular keyboards on the market - deserves a serious look.
What can I say - this looks and feels amazing to play. Comes with lots of backlit options which is great for customisation. Again, this keyboard warrants a serious look
