Input:
This is my first real espresso machine.  My biggest uncertainty before buying it was whether a manual lever-style machine or an automated one (like the Roncilio or Anita) would be best. What I have noticed in the first couple of weeks of use is that there is a huge amount of variability in the porosity of the coffee: using the same setting on my burr grinder, the same amount of coffee in the double-espresso cup, the same pressure when tamping, some types of coffee require much more force on the lever and have a much slower flow rate than other types.  For example, an italian-roast columbian was consistently extremely porous, while a full-city New Guinea Sigri was consistently extremely dense. It would surprise me if the automated machines dealt with this variability as effectively as you can with a manual lever machine.  I am very satisfied with this machine.  Other good points: it is small enough to fit under a shelf or low cabinet; it heats fully in just a few minutes. I was wondering how big a difference it might make to have a machine with a pressure gauge (the 16-cup Europiccola does, but the 8-cup model does not).  The green light on the machine that turns off when the right pressure and temperature have been reached seems perfectly adequate.
FOLLOW-UP: I've been using this machine daily now for 5 years. I've only had to take the head apart and replace gaskets one time, and it wasn't hard.  On older models (1990's) the cylinder liner was brass, but is now (Millenium model) nylon. Mine has cracked, which causes some leakage. Next time I do gaskets, I'll replace the sleeve too.
