The hobbiest solution is a Raspberry Pi with the Adafruit GPS.
It's surprisingly capable - I have a personal unit showing ~22 000 connected clients. Every time the score dips, it's because the upstream Cisco is at 100% CPU processing the NAT traffic to it.

With reports from of a 13.7usec step change - possibly coincidental with the decommissioning of GPS satellite SVN23 (PRN32) on 25-1-15 or other issues to with UTC correction parameters.

As an adjunct question, what sort of hardware are you using for your NTP
stratum 1 sources (GPS, atomic, whatever), and are there any which are
in the affordable range for the hobbyist?
