Hello all, new poster but I've been lurking here for a week or so.

So I bought my first, and only, mechanical keyboard. I purchased a Das Keyboard Model S Professional with media keys in May of 2010. I'm a pretty heavy gamer and probably an average typist. I love the MX-blues but most of my keys are completely shiny and over no textured resistance.
DK doesn't sell a full set of their keys. Will keys from wasdkeyboards.com fit properly and give the same feel that the DK keys once did?
Does anyone have any suggestions at prolonging the life of the keyboard? I already remove the keys and clean the keys and board yearly and clean that glossy finish about ever day. (Damn you glossy finish!)
One last question, Is there a way to tell, other then feel, if the keys are starting to let go? I now they say 50 million keystrokes but I'm a really heavy gamer so the left side of my keyboard has some really hard use. I probably won't go with DK again but that sleep function and the fact that it doesn't have a left windows key is what's made me keep it for so long.
