Mark,
I see some LEA-6T units and some NEO-M8N units. Has anyone done any timing
tests on these since they came up last time on time-nuts? The prices just seem
to be way on the low side.

One thing to consider about using a module with a built-in ceramic patch
antenna is that usually the antenna cannot be removed and the modules have no
support for an external antenna. If you do have problems getting a signal it
can be very difficult to add an external antenna. You might want to try moving
one around the house and seeing how well it works. It usually takes an indoor
GPS a while to acquire lock to the GPS satellites.
If you want a time-nutty-ish GPS receiver, search Ebay for "Ublox LEA6T".
There are some units available from China that have one (plus a ceramic
antenna) in them for a decent price ($30). Normally an LEA-6T GPS receiver is
over $100... But to get the full benefit of a GPS timing receiver requires
quite a bit of configuration and setup.
Another receiver worth looking into is one from the Ublox 8 series. They can
track and work with GPS, Glonass, Beidou, and other nav systems. Mine is
currently tracking 25 satellites (GPS/GLONASS/SBAS) with an indoor antenna. It
cost around $25 and came with a removable antenna. It has two programmable PPS
outputs (only one is brought out to the connector)... you can set one to 10
KHz.
