My compost bins don't look like my Avatar (pic) I built mine out of cedar and wire that has 2" x 3" holes. Yes it was a little pricey, but well worth it.
My compost consists of about 95% grass clippings from about 1.25 acres yard. I wanted bigger holes for the air to get in. I also put a stack down the middle. My bins are 4' X 4' X 4'. If you send me a PM with your personal email address, I will email you pics of them. If it is windy, sometimes mine leak out as well, but only the things that are real light in weight. In the summer I turn it every two weeks.
