[time-nuts] Is this a cesium frequency standard?

[paul swed]

OK have been staying clear of the replies.
Thats a lot of money for a RB of who knows what age and no support.
Those are $25 value items you are taking all of the risks. And yes indeed
you can get RBs for $25 a bit low in the lamp life. But do rejuvenate
nicely. FRS class.

Brand new ones I think from SRS are that cost, consume a fraction of the
power, great documentation, warranty, and modern control interfaces.
What on earth would shipping and customs be??
Cute boat anchor though a real waste of anything.
