The Garmin GPS18LVC is available for something like $85 US. An Oncore
M12 timing receiver with evaluation circuit board, is available from
http://www.synergy-gps.com/ for around $200 US. The Oncore used to be
made by Motorola; they discontinued it and it is now made by another
manufacturer. I have an Oncore and have found that it works very well.
More expensive receivers are available with metal cases, switches,
blinking lights etc. They may be worth the extra cost; the evaluation
board I bought doesn't even have holes that would permit it to be
mounted in a box.
Just be certain that the receivers you buy are designed for timing
service rather than navigation and have a Pulse per Second (PPS) output.
