What are the current available choices of silent switches?

I've been out of the loop for a while, and a *lot* of new switches seem to have appeared everywhere. I'm wondering if I could find a rundown somewhere.

As for my personal needs, I'm after a switch that's light, non-clicky, silent (the quietest possible, really), and as stable as possible (are there any quiet "box" switches?). I don't mind having to add o-rings or dampeners if that's the best solution.

Thanks!
