Any timing GPS which ouputs NMEA sentences and a PPS signal is supported
by the Generic NMEA driver in ntpd. You do need to have LinuxPPS support
in your kernel or use a helper such as gpsd.
If you want a drop-in solution you'll need something like

The GPS 18 LVC costs less than $70. Add to that the time for someone to
work out the wiring and solder up the connector (well under an hour for
a competant tech).
Any other solution is likely to cost more.
