Sub 100 pounds Mechanical Keyboard

Am looking for any budget mechanical keyboard up until now i only had membrane keyboards....SO YEH
My Budget is 90 pounds Right now i have these consideration...
-Azio Backlit Mechanical Gaming Keyboard (MGK1-K)
which is basicly a k70 clone with Kaihle Browns.
-Roccat Ryos MK Advanced UK Layout Mechanical Gaming Keyboard - MX Black
-Cooler Master SGK-4020-GKCM1-UK Quickfire TK "UK Layout, Cherry MX Brown Switches, Professional Gaming Keyboard, Mechanical, Tenkey" Black with White LED
-Cooler Master SGK-4020-GKCL1-UK Quickfire TK "UK Layout, Cherry MX Blue Switches, Professional Gaming Keyboard, Mechanical, Tenkey" Black with Blue LED

If you have any more keyboards that you would recommend please do tell..

I have a Quickfire TK with blues, and it is pretty good. Far from perfect, but it gets the job done. I like the compact design with the numpad but I have heard that some people find it hard to locate the correct keys on the numpad without looking. Three of the keys do not click, so don't have too high expectations on the quality.
If you are going to buy any of these I would recommend trying out all of the switches and buy a keyboard with those switches.
