@chlorox, there are many vintage machines available that are nice on compact yet make remarkable espresso. To name a few:
Arrarex Caravel……small basket, open boiler makes a really sweet ristretto
Pedretti Kim……..58mm pf and is also spring loaded
Bruni Brunella
I could go on! This is a really good site, full of information on vintage stuff and a pleasure to read if you want to pass a few minutes. It opens up on the Arrarex page but is easy to navigate
