Depends on your use case.  Also depends, today, on supply lines.  I would
avoid things shipped out of China as they may be a long time coming.  I
know many people with long unfulfilled orders...

Uputronics has nice bare boards, and Raspberry i HATs:

Shipping from UK is quick, and some USA stores have stock too.

There are other options if you are looking for higher levels of integration.
For example uputronics has a complete GPS/NTP server for about $250.

> Greg, to respond to your suggestion about using PPS without gpsd

I'll let Greg handle this one.
