[CQ-Contest] Help with a Kansas City Keyer

[Jim George]

I have used the KC Keyer as a way to send CW manually for many years,  and 
now all of my three (!) KC Keyes have problems. Most of the problems 
involve the membrane keypad having at least one non-functional key. In 
other words, when pressed there is no connection. Does anyone know of a 
person/place who can repair these wonderful little beasts? Let me know 
off-line.
Thanks in advance,
