Quite a good comparison and information on the different switches.
MX Blues are quite different, they are clicky and tactile like browns. I like Browns because the force is just right for me but i like tactile feedback. For linear switches i hear a lot of people prefer red switches to blacks as they have a lighter touch.
Dunno about your price range but QPAD, Steelseries and Corsair do some good value boards; Max Keyboard, Ducky, Zowie, Filco, Das, Deck are a little more expensive. I dont know anything about Coolermaster keyboards.
Not sure if it applies now but as i knew it Razer mechanical boards had build quality and reliability issues; they also have MX Blue switches which may be a factor in your choice.
