If its for your property where you live you could get away with one of thoes 5 galon bucket feeders, or if you are useing it during season where you will be seeing it every few days. I have made my own and works great. I still had to buy the feeder motor but used a 30 gal. plastic barrel with strait legs. It will hold 200 lbs of corn. For the most part you can get something that will keep the corn dry and put one of thoes feeder motors on it.
