I was looking for a good mill espresso machine (with non-pressurized filter), but is not an expert, I do not want to put a lot of money. MDF is a good choice in my opinion: it grinds the grain sufficiently fine, it is not bulky. As against the dispenser is not accurate and if you want to grind coffee for filter coffee Italian coffee maker or french press (that the mill may well do), the support carries non-removable filter prevents putting a container to recover under the coffee dispenser (or so a small container); but for an espresso is perfect
