So, if I take my nice clean 10 MHz, rig up a counter that counts to 
25,000, and a suitable PROM and DAC... (or run a DDS chip)... I think 
that would be a "clean and stable" 400 Hz.

Of course, for the more mechanically inclined.. what about a big 
flywheel driving an alternator.  You might be able to rejigger a car 
alternator.  I don't recall how many poles they have..you might have to 
spin it pretty fast.
