Hi
A number of us have Trimble TBolt’s that have been running for over 10 years.
The early HP’s (Z3801 … ) seem to have a weakness in the power supply section.
So far mine have come back to life after simple repairs. That puts the into the 20+
year range. The “Nortel” GPSDO’s seem to just keep on running and running.
That’s just looking at the devices that have been out there long enough / in big
enough quantities to look at “longevity”. It is by no means trying to say those parts
are any more reliable than others.
Simple answer is that a GPSDO is a pretty simple beast. You have a GPS module
of some sort. They seem to last a long time. You also have an OCXO, 20+ years is
a reasonable expectation on a modern part. There nothing like the Cs tube to
“wear out”.

Just about everybody on this list has extensive experience on GPSDO. Once it gets going, OCXOs are very reliable. I haven't had one fail, yet. There are plenty available on eBay, too, and if one is not too critical, anything will do for general lab use.
If this is your first time, my recommendation is a T-bolt. While they may not be the cheapest, there are plenty to choose from. There are vast amount of knowledge and experiences available. Well supported and no surprises. With add-on display board and all that, you can make yourself a nice self-contained unit for not much more than $300, depending on how well stocked your junk box is.
Personally, I tend to avoid ready-built eBay stuff.
