[Repeater-Builder] Used Outdoor Repeater Cabinets?

[Alexander N Tubonjic]

  Does anyone know of any sources for used outdoor repeater cabinets?
I've gotten permission from a local tower owner to locate an amateur
repeater on their tower but one of the stipulations was no access to
the existing equipment room. After a quick search of Tessco I see the
cheapest outdoor enclosure is going for around $2k. Does anyone know
where one could be found for cheap? Any information is greatly
appreciated, thanks.
