Hello, my personal thoughts of this would be either a Razer mechanical keyboard with brown, green, or orange cherry switches, or a logitech G110 keyboard.
If you want a mechanical keyboard that is very quiet yet still feel a good "bump", but you want to use it for a good amount of typing not just gaming, then i would recommend the MX Brown switch. If you are a very serious gamer and you can adjust for typing with no problem, then i would prefer the MX Brown or Orange switch made by Razer.
Brown cherry is a low noise switch while giving you a good feeling of the "bump" of pressing a key.
The G110 logitech keyboard which i own, is very scriptable for special effects or key commands, and the key press is great for non mechanical (very light on the fingers) which is great for both long term typing or gaming.
I am not up to date for any newer models that may be available, but this keyboard is good on cost too.
Both keyboards have backlighting, and i never use a light in my room rarely while using the computer, even for programming or designing.
Also this would be a great addition to my list, since this keyboard has new switches invented specifically for gaming.
