Filco majestouch, doesn't have any blue lights but it has mechanical switches and comes in at around £110.
Had a few logitech keyboards in the past and non are as comfortable as this with cherry MX brown switches.
Great keyboard I have one with browns and it is such a pleasure to type on compared to regular keyboards, I like they way it is nice and compact, like the dells ones. Very sturdy, nice bit of weight to it.
Also for gaming they are amazing, the point where they key is press has a bump which is half way down so you know you have pressed the button, this allows you to be more precise with the board and know they you've pressed the button.
Oh yeah and also has 3 blue LEDs for NumLock, CapsLock, ScrollLock
The Filco vs Razer for gaming is a no brainer, the Razer does not have full NKey Rollover which means you can't press all the buttons on your keyboard at once. I play the odd bit of trackmania, where on the razer board you wouldn't be able to press all the arrow keys at once.
Anyway keep mechanical in mind, does lack features such as media controls but you can set the binds up yourself for that, some of my num pad is used for next track etc.
Its worth trying a mechanical, you don't know what you've been missing..
Too the argument in this thread, its personal choice, many people have not been able to try a mechanical board, but gamer boards do they their use as well.
