I own the gaming keyboard (but not the keyset, I dont play MOH). The keyboard itself is great. The keys were bulky compared to my old scissor switch keyboard, but I got used to it pretty quick. There is nothing mind blowing about it, and it wont make you better at games, but it is a decent piece of hardware at a great deal. I paid $84 for it on amazon (after doing weeks of research) and have yet to regret it.
The only keyboards that can beat this would be a mechanical keyboard, but those are impossible to find for <100 unless you get a razor one on a deal. However, I read reviews about sticking keys and bad ergonomic design on it. Realistically, to get close to the same quality, youre looking at $150-$250.
This is ideal for the moderate to heavy gamer, and at this price point even the light gamer. I only game about 1-1.5hr a day average these days (not much compared to a lot of people). I don't compete in tournaments or anything like that, I just wanted something more reliable and professional.
I have also never had to return or had any issues with a steelseries product. I am a huge fan of the company and to date I have their keyboard, mouse, mousepad, and three sets of headphones. Again, no issues with anything. They are a Danish company though and relatively small (they cater pretty exclusively to hardcore clients), so service might not be amazingly fast, but still adequate.
