if you ever find yourself deciding betwen something cheap and something a bit more pricey take a minute to ponder how, when and where the product is produced. Trawled prawns and salt water crayfish is sheaper, yes, but for the fish population its devastating. This litte one is a mare baby but gets caught in the nets with the fully grown crayfish. The result is fewer and fewer crayfish. With pods/cages this fellow is safe. Its a bit more expensive, but better for the waterlife.
