The budget single-dose fight comes down to burr geometry. The DF54, listed at $230.00, runs custom 54 mm stainless flat burrs at 1400 RPM with a bellows-assisted near-zero retention path. Fellow's Opus 2 at $199.95 answers with 48 mm conical burrs, a stepless dial, and the more polished domestic package. Flat burrs tend toward clarity and consistency in espresso; the Opus 2 counters with usability. Thirty dollars separates them, so pick on burrs and workflow.

Why flat burrs matter at this price
Flat burrs produce a tighter particle distribution, which in espresso reads as cleaner separation of flavors and easier repeatability once dialed. The DF54's custom 54 mm flats spin at 1400 RPM and feed through an anti-clumping chute with a bellows to blow the last grounds clear. A few years ago flat-burr single dosers started at twice this money, which is exactly why the DF54 earned its following. Our full DF54 review covers it shot by shot.
Why the Opus 2 is still the smoother own
Fellow ships tighter industrial design, quieter operation, grind guidance printed on the load bin lid, a 2 year warranty against the DF's 1, and wide retail availability. Conical burrs give a rounder, blend-friendly cup that plenty of palates prefer for milk drinks. The DF54 is the enthusiast's pick; the Opus 2 is the recommendation you give a friend who just wants it to work.
Which one should you buy
Buy the DF54 if espresso clarity per dollar is the mission and you do not mind a more utilitarian machine from a direct-import brand. It is the cheapest credible flat-burr single doser going.
Buy the Fellow Opus 2 if you value fit, finish, quiet, warranty length, and a gentler learning curve. It gives up a little espresso resolution and returns it in daily pleasantness.
