i just bought and put out a new type moultrie feeder for 25$ out of bass pro . its a 5 gallon camo bucket with a small type varmint cage on the bottom and the hole where the corn comes out is blocked by a heavy rubber ball. i like the fact that theres no batteries needed. when the deer pushes against it it lets out a little corn. i was thinking of calling them to see about buying just the cage part so i can mount it to my own barrels and 30 gal garbage cans. it attaches easily to the can with 3 nuts and bolts. if they sell the cage seperatly i cant imagine costing more than 10-15$
