I have a spare keyboard if you need one. It is a plain jane model from a Dell. It is black and about as small of a footprint as it can be with all the keys one needs. This style has been used in offices and millions have been produced, I'm sure. It has the typical USB plug interface. We buy our computers from our local school when they upgrade and get good deals on this equipment.
I'm not sure you'd even get it if I was to try to mail it to you, remembering reading about some of your packages being pilfered down there in the mail...
Unless you're on a laptop...then never mind...sorry to hear about your troubles.
