Well, that I do not know. The majority of Ku & Ka LNBs for home TV use are
using free running DRO's. I have a bunch of them, and never ran across any
locked ones, except for some of the ones used for internet service. My real
experience is what we use in military satcom terminals at Ku and Ka bands,
with apertures from 0.6 to 9.2 meters, and they are all locked to an
external 10 MHz reference. I doubt if you will see any major dumping of
those. Especially now, because of strict ITAR. Even if one can buy it
directly from the manufacturer, once the military has owned it, they will
probably dispose of it in such a way that we will not see them on ebay.

Ah.. but the question is really not whether the "new" price is cheap, 
but whether there's some reason why someone would be doing a massive 
refit, and dumping lots of these on the market surplus.
