If I were to purchase a used rotor o would want to have it reconditioned. So
the cost for the rotor plus the cost of recondition would still have to be less
than the cost of a new one by some factor. Chuck K9LC

than half the new price.Think of these in terms of:1) what was the original
warranty (I assume you're selling as-is)2) What is the design life? What's the
wear out component and how much of its life is left?This is kind of tricky -
there are plenty of electric motors out there that are 100 years old and still
working - but that doesn't mean that they were designed to last that long - you
might have gotten lucky, or the loads were low, etc.In the case of used gear
you don't really know the history - sure, the ham selling it to you (if alive)
will say that it was never abused, but oh yeah, there was that wind storm 10
years ago which bent a bunch of the elements on his antenna. Nobody has *real*
usage data (like you would with a regularly monitored mechanical system).I
would think that the wear out parts are things like bearings, seals, feedback
pots, etc. What affects its wearout? temperature, ice, water, mechanical loads.
These are all hard to estimate. It's not like a car engine, where you've got X
hours of running at Y RPM, against a rated bearing life of Z hours.I would
assume, without other information, that the useful life of something like this
is 10-15 years - I can't imagine a company *designing* for a 20 year life for a
piece of consumer gear. Therefore, the 15 year old one is basically at "scrap
value" - what are the parts inside worth if someone wanted to use it to fix
something else, or if they were going to sell it as scrap metal. If someone
happened to need the control box, or the connectors on the cables, it might be
worth a bit more *to that one person*.The 2 year old one that's been outside,
but not operated? A lot would depend on the environment, and what the seals are
like. It's probably not "worn out", but if something sits, unmoving, through
rain, ice, sun beating on it, etc., it might have developed leaks, or the
elastomers have gotten stiff.It's not under warranty. Maybe half the new price
if *everything* is like new and there's no obvious damage.At some point, too,
you've got to decide if shipping 40-50 lbs is worth it. Shipping UPS for
something that size is about $75-80 depending on where it's going. There are
