Srin85 Greetings….on the forum there are plenty of Elizabeth owners, hardly any (if indeed any) Gaggia and Profitec owners. Therefore expect folks to tell you about their Liz. Indeed, I own one. My last machine broke and I wanted to prove to myself and anyone else who would listen, that you do not need an expensive machine to make good coffee (but a decent grinder does help).
There are plenty of threads on here for the Elizabeth. try and search for them. But to sum up, small and portable, twin boiler, can supply hot water without the steam boiler being on, 58mm, pid….what more do you need!
