JonWoo187 I considered the Silvia Pro X, but after seeing the reviews, the drip tray put me off - small things, but important to be happy - so I ended up with my ECM Classika PID, which I’m very happy with (The added flow control is a bonus).
There is so much to be said for good build quality and workflow, and absolutely upgrades need a lot of research - ideally hands-on, but for many of us that’s almost impossible. Having said that, I’m hoping I don’t find a need to upgrade personally now. I see these shiny ACS machines, but honestly they wouldn’t be any better for me - just fancy buttons and levers 😉
Back to the original post, it does sound like a dual-boiler for the milk aspect, but I’d absolutely suggest watching videos and reviews especially around workflow and how it fits your expectations. I know that my workflow actually became much simpler when I went to E61 after the Bambino, but that’s more because the Bambino couldn’t hold temperature, didn’t have a shot timer, didn’t have a 3-way solenoid, etc… little things (well, not the temperature) but you have to put more effort in to get to the same place.
Sure, the E61 takes around 45 mins to heat, but I make a glass of water when I wake and switch on the machine, then when I’m ready for coffee it’s good to go. You just need what best fits in your daily flow.
