You can make them fairly inexpensively and in a few days time. They do hold up well and I have had mine now for about 2-3 years without a problem. The fish love them and the wildlife (frogs, ducks...etc) also love using them. Its also a great way to keep your tie off line to your bubbler system anchored to something.
