David,
The FE-5680A is always plentiful, and a lot of them are generally mounted
on a PC board, from pulls, along with having a decent price. The main thing
is availability, which means spare parts if you need them. I also know that
I've seen these used as internal timebases for counters before on the
larger HP types.
I decided to get the FE-5680A in the end. I found a seller willing to accept
£75 (~$120) for a pair of them shipped to my house in the UK. At $60 each
(including shipping), I thought that was a fair price.
If at a later date I decide I want something with higher performance, I'll
reevaluate the situation.
I don't have a need for high absolute accuracy, but I'd like to have something
better than an HP10811A (or similar) that has not been calibrated for a decade
or two.
I've got a Kenwood TS-940S transceiver with the rare SO-1 TCXO installed.
According to the spectrum analyser, that is about 40 Hz off, but I've no idea
how much of that difference is due to the transceiver or HP10811A oscillator in
the analyser. Logic would suggest the oven should be better, but that has not
been calibrated for years, so the crystal has no doubt aged.
A non-disiplied rubidium is not state of the art, but I'd feel comfortable in
setting both the transceivers TCXO and the analyser's OCXO to the rubidium.
