Breville Barista Express
54 mm (2.13 in) portafilter · built-in conical burr · 2 L tank
Machine and grinder in one box, at a price that undercuts buying them separately. The compromises are real — 54 mm (2.13 in) basket, single boiler, a grinder you will outgrow — but nothing else takes a beginner this far this cheaply.
Best for: Your first portafilter machine, if you want one purchase rather than a project.
