Yeah they let the machine do some of the science but your still making espresso.
Coffee kev on YouTube is good and he will run through different machines pros cons etc. or his website coffee blog). Think
@Kenny has a ninja luxe and loves it. Probably a good choice for you if you want to spend £500, pretty sure it has auto frother as well.
I have a sage bambino plus and separate coffee grinder but I enjoy the process and science of making espresso, so that’s not for you unless you want to get into home barista (it’s fun I promise). My parents have a sage barista express, but that isn’t good for them because they don’t want to be baristas. They’d have been better off with the ninja luxe/sage barista express impress etc.
Long story short, I think something like the ninja luxe will be good for you.
