It so isn't like the G15. It does have low keys if this is a concern, but it's a stunning keyboard. It does have quite a 'harsh' feel to it, but in a feedback way, not in a mush of randomness like most of the gaming keyboards do, the G15 included.
Why people only spend £30 on mice and keyboards, yet hundreds on the rest of the PC, I cannot understand. Them and your monitor are the most important parts of the PC by miles and miles. You don't handle or look at your RAM for several hours a day, so why spend 3 times as much on it? It's the same with why some (it doesn't sound like you) concern themselves with the aesthetics of their peripherals... erm...
