Using a OXCO allows the instrument to be moved around to various
locations.  The GPSDO requires the instrument to be tethered to a roof
mounted antenna.

There is also the matter a "trust".   I would not trust the accuracy
of a $100 GPSDO bought on eBay unless I had some means of monitoring
it.  So the GPSDO plan is more expensive because I'd guess that you'd
need at least two of them and hopefully not two identical units.
