If you do go with a new keyboard, may I suggest Logitech?

I'm looking for a new keyboard -- mine's covered in keyboard plaque, and it'd be cheaper to get a new one than to clean it. The problem is that I don't want to buy one without trying it. I like the feel of the one I've already got -- just the right mix between clackiness and softness.

Of course, I'd try to get another one like it, but they've stopped making this model apparently. In fact, the online retailers I've checked seem to only stock those funky whizz-bang, does everything, IR/bluetooth/softkey ones. I want a standard 105-key UK keyboard, dammit. PS/2 so that it'll work with my KVM.

Rant over.
