drdre89 Vostok and Evos are extraction monsters. So is Nurri. They give a great repeatable cup.
Since you talk about Bambino, it is a decent machine, if you pair it with a good grinder, filtered water, and nice beans.
Interestingly, the following is just my experience:
If you prefer drinking just espresso, if you aren’t careful, you might find the espresso from the above levers over extracted at 1:2.5 than at 1:2 even for lighter roasts.
I have had light roasts on the Evo1 along with Sage Bambino both using the same grinder (Duo) side by side. Tbh, I find the espresso from Bambino more enjoyable than from Evo. 🤷🏽
I mostly drink filter, whereas Evo does the week end duty for Americanos and flat whites. However, I always drink espresso from Bambino. 😊
Please take your time, buy once and buy well. It is a lot of money. GL with your purchase.
