Watch the thread on this list about the Arduino based GPSDO.  I think
you can get the price down to $50.  If all you need is something to
calibrate frequency counter then all you need is  9 to 10 digit
accuracy

I'm going to do this just to prove it can be done for a low two figure
price.  But first I have to find a decent crystal oscillator that does
not use up 1/2 of my $40 budget.

If you want ultimate precision that you need a good GPS antenna in a
good location,  A high-end timing mode GPS receiver and a high-end
double oven quartz oscillator.  The cost adds up.   But I think if you
relax the specifications and shoot only for 9 to 10 digits you can
greatly reduce the price.
