[time-nuts] Question for the cesium nuts.

[Keith E. Brandt, M.D.]

What about rubidium standards? Are they more common due to lower price?

Speaking of which, Ebay has several "Rubidium atomic clock smallest 
cell frequency standard" listed for US$20. What are these modules?

Goodbye cruel world that was my home-
   there's cleaner space out here to roam
Put my feet up on the moons of Mars-
   sit back, relax, and count the stars
