I've played with several of the pulled oscillators.  They're nothing 
special -- xDEV at most frequencies for the ones I've seen is around 
5-20x worse than an HP 10811.  I tested them after they had been running 
for 2-3 weeks -- I've never taken the time to let one settle for months 
or years -- so some long-term improvement may be possible.  But I doubt 
that the ones I've seen would ever equal a 10811.

Best regards,
