I have a Meinberg M600, and have no complaints. (I've not managed to
get Dell OS10 to synchronise to it, but I think that is a Dell problem
rather than a Meinberg problem. Aristas, Linux-PTP etc. have no
problem with it.)
I'll give another vote to the Meinberg kit. We had both M600 and M1000
w/ NTP+PTP at $dayjob-1 and they worked well (GNSS-sourced, with
upgraded-but-still-quartz clocks).
Depending on your holdover requirements you might need external
frequency references beyond what Meinberg can do - their top-end clock
is still rubidium, not caesium. Then you're back to
Microsemi/Oscilloquartz. But if you're looking at less drastic
requirements, either for holdover or stability, the Meinberg stuff is
reliable.
Cheers,
