Below are some comments from Said:

The published schematics only showed the DC-to-DC switcher version, sounds
like the TCXO version should have better PN and spur performance with an
LDO.

One recent post caught my attention, and here are my comments.
There are some serious basic design issues with Nick Sayers’ GPSDO hack

BTW I have a '58503A' from him. It did and does (a year later) still work,
although it took me a while to get it going. But it was a bit iffy - obviously
in a re-made case and the eBay images
I searched the list archives and found some discussion mid-to-late
last year about several inexpensive GPSDO's made by bg7tbl. It seems
that all of the better models (according to discussion on the EEVBlog
forum) are gone.
I do find two similar units currently listed:
That last one sure looks interesting. I have one that is similar to the
Trimble units that have been discussed, but was made by Symmetricom. About
all I can say right now is that it *seems to work. I'll know more after I
have compared it to the Z3801.*

The last you mention is a FEI PicoSync with the even second (PP2S)
output. Usually, for time-nuts purposes (and if it will be your first
GPSDO), it is better to have a pulse-per-second (PPS) output,
