Best espresso machines under $600
A larger machine budget expands the roster, but it does not make accessories interchangeable. Group size and fitting style still determine the available upgrade path, so we separate deep, moderate and thin ecosystems using the classifications in our machine passports.
Group placement comes straight from our machine passports. Within each group, machines are ordered by beginner-friendliness, then by name when scores tie - not by price or review scores.

We have not physically tested these products; all compatibility analysis is based on manufacturer specifications and publicly available listing data. "Seller-claimed" means a marketplace listing asserts the fit; it is not manufacturer-confirmed. Verify size against your machine before purchase.
Deep accessory ecosystem
Standard 54mm or 58mm groups with full third-party support - bottomless portafilters, precision baskets, tampers and distributors are all easy to find.
Moderate ecosystem
Real third-party support with caveats - some accessory categories are well covered, others take more searching or brand-specific parts.
Thin ecosystem - know before you buy
51mm or brand-specific groups with a limited upgrade path. Thin describes accessory availability, not beverage performance - but you do give up most of the third-party accessory catalog.
