What is the best beginner espresso machine?

For beginners, the Breville Bambino Plus ($500) is a strong recommendation: it heats up in 3 seconds, has automatic milk texturing, and is forgiving of grind inconsistencies. The Breville Barista Express ($700) is great if you want machine + grinder bundled together to reduce decision fatigue. Avoid machines with non-pressurized baskets at entry level until your technique is consistent — pressurized baskets are more forgiving.
