Hi

Talking about rubidium standards. 

Does anyone have any experience with buying and using the EFRATOM LPRO-101 rubidium standard that  seems to be readily available from  the many Chinese sellers on Ebay?

I am tossing up between the LPRO rubidium  and the Thunderbolt GPS standard. The Thunderbolt  makes a lot of sense since it  does  not depend on a tube that can wear out or go out of lock.

Will Elecraft be producing both the frequency standard and the interface or just the interface?
