Have you tried AVNet?

Does anyone know how to actually *buy* one of these little gems?

I first read about them well over a year or so ago and requested information
several times but never got anything more informative than the press release
that was on the web site printed out on paper.

they are owned by Microsemi now and the web site shows some very spiffy stuff,
not the least of which are GPS-disciplined rubidium and cesium clocks using
their leeeetle bitty Rb and Cs devices. and the whole thing is small.
