I am looking at these 4 machines.

ExpoBar G10 2G compact
Astoria Perla 2G compact
Casadio Dieci 2G compact
Iberital Intenz 2G compact
Nuovo Simoneilli Applia 2G compact

Is there any difference in the coffee brewed by these four machines?
Casadio is propably the cheapest but also slightly has a somewhat smaller boiler.

Has anyone exprience with 2-4 machines above? I think I'll get a pre-owned one.
