Welcome to the ‘dark/lunatic side’
As someone who also jumped from a fully automated machines (Gaggia Titanium and Delonghi Magnifica) to a Vesuvius Evo Leva, you’re in for a very nice ride whether you go for it or the -still unknown- Nurri Leva.., Once you’ve made the switch, it will be very hard to return to your fully automatic machine. You’ll also find that tuning a big lever machine, especially with a single dose grinder, is much easier, as is steaming.
Make sure you do get a good grinder (I have a Niche Zero which I’m happy with) and find a way to get good water (Descaling is best avoided with the double boiler machines you’re considering)…
