A few years ago I purchased a Motorola Oncore UT board from
www.tapr.org for about $130 or so. They also sold me an interface
board for around $30. The interface provided a power regulator
and serial port logic for the Oncore.
I did a little soldering, dropped it all into an inexpensive
plastic case, and now I have a stratum-1 NTP server.
It still works today (he says while knocking on wood...) :-)
Tapr no longer sells the UT but it seems that they still have
some old GT boards. Another alternative is the Garmin GPS-25,
it looks like tapr still sells the interface board for that.
I almost got that one but I decided on the UT instead.
