Qiuet Keyboards with Tactile Feedback?

zerOnIne asks: "Like many geeks I know, I love good old clicky mechanical tactile-feedback keyboards. I've got an IBM Model M (101 key) on the server, and a Linux CoolKeyboard on my desktop, and I wouldn't want to part with them. The problem is, though, that my wife and I live in a studio apartment, and my desk is necessarily right next to the bed alcove. This poses a problem on nights, like tonight, when I want to get some late-night hacking in, and she needs to get some sleep: my typing can rather loud if I get going. Is there a keyboard out there that can give me the mechanical feel of an IBM-101, but without the noise? As an aside note, whatever happened to the Linux CoolKeyboards company?"
