My work keyboard has red (linear) switches which are slightly quieter than my neighboring coworker's membrane keyboard. I've been thinking about getting some O-rings so it can be basically silent.
Honestly I think a good enough membrane keyboard is probably good enough. Above a certain baseline functionality, keyboards are all about preference. I like the ones that come with HP business desktops (model KU-0316), which tend to be pretty consistent. I've heard lots of good things about Logitech, but my only recent experience is with the MK320. It's decent for typing but has a weird nav key arrangement.
