Bean Not the biggest fan of the Breville grinder for espresso. Rocky is a very solid grinder but not adjustable to a micro level. With the Preciso by Baratza, fully adjustable not as well built as the Rocky, but gives a better grind. The Baratza Vario is my favorite and makes by far the best espresso. It is the way to go. Read all the Forums and you will see I am correct.
