I flew a 100MHz EX-421 in space on a cubesat - same series of tiny OCXOs 
- except the EX421 is a bit smaller foot print and taller. it's about 
the size of a US sugar cube (13x13 mm and 10mm tall). Low power for an 
OCXO, and small, both of which were important. And the phase noise was 
decent. They weren't too expensive (a few hundred $ each, as I recall - 
non space grade).
