Mark's Law of Rubidium Goodness... the bigger the box, the better it is.  The HP5065A is one of the best units ever made.  It can rival a cesium beam unit.  The X72 is a horrid little creature.


I would also go with the M100 / FRK units.   The LPRO an FE56xx units were designed for telecom use and meet the specs required of them and low cost.   The M100 and FRKs saw a lot of use in military systems.

Which one you choose is best determined by your budget,  applications, and requirements.  A noisy little X72 could be just fine,  or you may need the beastly HP5065.
