If you maintain a decent test bench and go the route of getting a Rb reference you will eventually find reasons to attach all sorts of 10 MHz devices to it. I use it on counters, scopes, frequency selective voltmeters and other analyzers.
I leave the Rb reference running all the time. It is even attached to a 24 VDC battery to keep it going during power glitches. With some additional devices I can do much of my own metrology and calibrate my own gear.
