The Garmin GPS 18 LVC (or whatever) is under US$80. You'd have to check
with other folks about the prices of different units.
Then it's a function of local reality.
Is it practical to run an antenna wire from your NTP machine to a GPS unit?
Is it practical to put a (possibly very small) machine near the unit and run
a network cable (or a wireless connection)?
Do you have electricity "close enough" to your GPS unit to allow this?
What about using a CDMA refclock instead?
What about using one of the modem drivers?
What about getting a decent ATOM refclock and using that?
Just be open to the possibilities.
You will probably hit constraints along each path. Just keep trying
diffrent paths and look at the costs/benefits of each choice, and be
flexible and creative in how you look for solutions.
The bottom line is you're gonna need a source of time, a way to talk to it,
and some number of machines that will distribute that information to other
