Hi there!
I'm not a time nut, but almost. I like my equipment to go at the same rythm, so I spent about €200 on two boxes: a GPSDO and an 8-output distribution amplifier and I am very happy with the result. My frequency measurements are precise and synchronized enough. Those were bought at eBay, from China, you know, that green and aluminum small boxes.
Regards,
Ruben
