Pete, I will be using it for a general lab standard, to feed into other test equipment. But, I can't predict my future usage, so I want the best that I can get. I also plan on eventually locking it to a GPS (probably a U-Blox board).
I am retired, so my budget is nearly non-existent. :-) I have to spread the cost around, so cheaper is better even if I then have to spend extra later. The HP 5065A that Paul found at 1800 EUR is very much out of range. A new PRS10 is only 1495! I am considering a PRS10 or LSD12 that needs repair. Schematics are available, the ones available are within the 20 year life span of the rubidium bulb and are much more affordable than a working unit. It is, of course, a gamble. Right now, I am researching. Actual purchase will be later once I decide which way to go and budget the money. I may need other things first (a power supply springs to mind). I researched the scope that I wanted to buy for a couple of months before I pulled the trigger. It blew within 5 minutes, but fortunately only needed recapping. I also made a few other modifications while I was at it. It still needs calibration. All that took another three months after purchasing.
