The most consequential $250 in home espresso, and the part of the setup most people fund last.
Under $300 the DF54 is the most capable espresso grinder — 54mm flat burrs with stepless adjustment — and the Baratza Encore ESP is the safest first buy, with twenty of its forty settings inside the espresso range and parts you can actually get.

Grinders under $300 that reach espresso with enough resolution to dial in — not merely "grind fine". Ranked on our control rating, which counts stepless adjustment, the number of settings, burr diameter and, for hand grinders, the published micron step.
Excluded: grinders whose espresso range is one or two clicks at the very end of their travel. They technically reach espresso and leave you nowhere to go.
Resolution, mostly. Every grinder here will produce coffee fine enough for espresso. The difference is whether you can move in steps small enough to turn a 45-second shot into a 28-second one without overshooting.
The DF54 is stepless, so there are no steps to overshoot. That is the single biggest reason it leads, and 54mm flat burrs at this price were not available a few years ago.
The Encore ESP is stepped, but Baratza divides its forty settings so that 1–20 are the espresso range — twenty usable positions where most grinders give you three. It is also the one here with a proper spare parts catalogue behind it, which is why it remains the standard first answer.
The 1Zpresso J-Ultra publishes 8 microns per click with 100 clicks per rotation. On resolution it beats both of the above. It is also a hand grinder, and you should be honest with yourself about that.
Stepless adjustment has no reference numbers. You will keep your own notes, or a mark on the dial, and switching between two coffees means finding the setting again. Stepped grinders trade a little precision for the ability to say "setting 12" and mean it.
Neither is better. They suit different temperaments.
The Breville Smart Grinder Pro has sixty settings and doses directly into 54mm and 58mm portafilters, and it grinds for filter as well. If it is going to be your only grinder for every brew method, it is the more useful machine. If it is only ever grinding espresso, its sixty settings are spread too thinly across the range.
Chosen against the criteria above. Every specification links to its source.
54mm flat burrs, stepless adjustment and a true single-dose design, at a price that used to buy a stepped conical. The clearest value in espresso grinding right now.
The default first espresso grinder. Half of its forty settings sit inside the espresso range, which is the whole point — most cheap grinders reach espresso only at the very end of their travel, leaving nowhere to dial in.
A hand grinder with 8-micron adjustment steps and 48mm coated burrs. You supply the motor, and in exchange you get espresso resolution that costs several times as much in an electric grinder.

Yes. The 1Zpresso J-Ultra publishes 8 microns per click, which is finer adjustment than most electric grinders at any price. The cost is about a minute of effort, every shot.
You can, and for many people it is enough. Integrated grinders offer between 15 and 45 settings and cannot be replaced independently, which is the trade you are making.
