I agree.  What K9CT and other large "distance to tower" contest stations 
do.  Intermediate supports, fragility, big birds, weather, tree falls, 
... a lot will go wrong.

One thing I observed in the past (>3yrs ago) looking for surplus 
hardline was that the larger diameters (>7/8) are sold at a bigger 
discount.  Connectors get expensive, but only two are needed.

A factor impacting the market is new cell towers don't use much hardline 
any more, all the RF stuff is at the top in the antennas.
