David, Hal,
Thank you very much for the pointers, and the hand-holding.
I ordered a unit from Sure last month, which arrived last week. I used
David's excellent instructions, and I am happy to report that the unit
(cabled to a 1U Linux server, Debian testing) is working well (or so I
think).

please?
There are two obvious choices. A bit of googling may find more details

Does this provide 10 MHz or 1pps?
None of the low-cost units that I know about provide 10 MHz.
Most of them provide crappy timing via NMEA over a serial port.
The ones I mentioned include PPS.

So the 16x manual says. As far as I know, all of the Garmin LVC, HVC,
and 5Hz versions of their receivers have a timing pulse output.
The GPS18 series that I have was replaced by the GPS18x series.
Some of their receivers have TIA-232-F (RS-232)

There is another variable to consider: cold start vs warm start. If it

Tried you suggested test, and re-acquisition was fast - yes, it has battery
backup; a feature I now consider essential!
Has anybody done any studies on acquisition time vs time since solid contact?
