We picked one up for $50 from a local farmer who was using it as part of an automatic watering system for his chickens. We use it for emergency backup for animal water in case the power goes out (which happens on a regular basis out here).
I invested another five dollars for a galvanized nipple and a brass boiler drain so we could hook a garden hose to it.
