To a large degree it depends on what you want to use it for. HP 5065 is  
considered top of the line and PRS 10 is a very nice Rb but lately I have seen 
 lamp oscillator failures. I like FRK, well documented easy to modify and 
if done  right super performance.
As part of a GPSDO project using the FE 5680A that my Swiss friend Juerg  
and I have worked on for a year and is now in Beta test is also an  
alternative. We are done with FE 5680A so Juerg has his along with a GPSDO for  sale. 
If you want a affordable Rb that has GPS control that is an alternative.  
Unit has less than 6 month running time so like new.

Hello  All,

Can I have your recommendation regarding a choice of 10  MHz rubidium source
(available now on eBay like FE-5680; LPRO-101; LPFRS;  FRS etc.) as a
reference signal for my frequency counter Pendulum CNT-91.  

Thanks in advance.
