If you go to the Garmin web site and look at their OEM page, you can order the
OEM versions for around $55 from Garmin directly.  I have one of their models, a
15xx OEM module (including the pigtail cable).  It has PPS stated as good to 1us
but I was told it was actually good to 100ns with SA turned off.  It is not
designed to be a "timing" receiver, but will get you in the ball park for a cheap
price.  You will still need to get an antenna of some sort, supply power and use
software in a PC to setup and control the unit.

I purchased the Garmin 15 to use in my car, as my main GPS unit developed a
failure.  I was using my main unit to drive my laptop software for mapping
purposes.  The Garmin 15 will replace it.
