I would HIGHLY recommend that you buy a GPS disciplined oscillator. You can pick up a Trimble Thunderbolt on Ebay for less than $150 from the Chinese sellers (or $300 ready to go with power supply and antenna which you can buy for a lot less). The frequency output of these can rival that of a cesium beam unit. You will need one to set the frequency of the rubidium oscillator.
I would avoid the Lucent units. They are poorly documented, very big, and most cannot be made to properly lock the oscillator to the GPS signal.
