So far the ONLY non Digi-Key off the shelf part I am suggesting is the
enclosure. It meets both horizontal and vertical EuroBus standards.

I am with Lyle.  PLEASE let's adopt standard connectors and controls 
that are available from standard sources in small quantities and mounted 
on the circuit board!  I don't need a full kit.  What I need is to not 
have to figure, scrounge,  drill,  saw,  poke,  curse, ...  I just don't 
have time and I am trying to quit (the latter).
