I have used a 4x4 keypad, slightly less than 3"x3", made by Digitran
Company, Pasadena, CA.  Their part no is minikey KL0088 9318.  There
is no fancy thing on it,no labels, just 16 tiny buttons.  I paid C$2 each in
Toronto.  Sorry, I don't have detail info to contact.  The problem
with most 4x4 keypads is the labelling, not in HEX notation if that's
what you want.
