I have used duck decoys and pool floats, and have settled on plastic bottles (screw lids sealed with silicone bathtub sealer) as a low cost float. Don't use milk bottles - that plastic deteriorates in a couple of months outdoors. Other types average about 2 years before Winter ice holes them. I used a 2 liter Mountain Dew bottle last year, and it is still good.

Use polypropylene rope - it floats and helps you replace missing bottles/floats.
