Low cost GPS receiver?

[Hal Murray]

Is there a popular low cost GPS receiver that requires (at most) only moderate 
amounts of soldering?

If I had asked 20(?) years ago, the answer would have been Garmin GPS-18.

I'm looking for something with a good PPS.  I'm assuming it goes in via a 
modem control signal on a serial port.  So USB is out.  I'm interested in 
PCs/servers that have PCI slots.

Half the battle is power.  I'm happy to steal power from USB.

I have a couple of PCI/Serial cards with a jumper option to supply 5 or 12 
volts.  (I'll have to check which pin the power comes out on.)


There are several GPS-HATs for Raspberry Pi.  Does anybody have an up to date 
list?
The PPS goes in via GPIP.  It works well.  The Pi 4 has a real (not USB) 
Ethernet.  It makes a good NTP server.
