Keyboard?

[IceFire]

For ages I've used my trustworthy Microsoft Natural keyboard. It's probably over 10 years old. The best part about it is that it's a fairly straightforward keyboard with really good function keys. Problem is I think it may be wearing out.

So what is a good simming keyboard? Some of the new keyboards look nice but the function keys are really aweful. Looking for a blend of quietness and a good price too.

Suggestions?

EDIT: Does anyone have this keyboard? http://www.logitech.com/en-ca/keyboa...d/devices/5902
