GPS can be done very affordably and can offer great time.  There are
several *potential* pitfalls:

- It is *possible* for the US Gov't to detune the GPS system (locally or
  in-general).  Since GPS is now increasingly used for "human safety"
  things, the costs/risks for doing this have gone up significantly so
  this risk may now be more of a threat than a reality

- bugs happen, and relying on one of anything can cause a problem.  If
  you have enough souces of time, ntpd will throw away information from
  a source (including GPS) that it does not believe.

There are other potential failure modes as well, but most everything has
these issues.
