I sure ain't no expert , never having a espresso maker, but I got an aero press and my coffee is a whole lot better than it was , if a 10 k machine makes it that much better, I,ll have to try it, but all in all I think the areopress makes a real mean 4 shot cup! Tc
I used an aeropress for years before getting a real espresso machine. The aeropress can't make real espresso, but makes really great coffee. I wouldn't call it better, just different. I still use the aeropress from time to time especially if I want iced coffee.
