I tried out this machine last year and I can say (as someone using a Silva 10 years) that this machine is wonderful. For sure there is a big difference once you know what you are doing. My next will be either that machine or something similar. With someone who knows how to make an espresso and froth, you can be 100% in no time.
Trial and error will waste a lot of coffee beans which can be expensive. Over the years I get less picky about beans since most of what I brew are lattes vs. just espresso. I keep it the Euro size cup so it's still a robust drink.
