I been seeing several posts regarding keys, and was wondering if there is a source to purchase just a replacement rubber (silicone?) membrane for buttons. I have 2 fully functional keys, but the rubber is starting to show slight signs of age (crack, discolor), other than that, the keys are mint. Seems a shame to purchase 2 new keys just for a cosmetic fix.
Perhaps I am just being picky, but it's all in the details ya know.
