55mm flat burrs and near-silent operation at a mid-range price.
The Silenzio is the Eureka Mignon you buy when you want the excellent 55mm flat burrs and silent grinding of the Specialita, but you can live without the digital timed dosing display. Instead of the touchscreen, you get a simple manual timer knob — set it once, and it doses the same amount each time. In practice, this works fine for most people. The grind quality is identical to the Specialita (same burrs, same motor, same anti-clump system), and the noise level is the same impressively low ~55dB. The Silenzio saves you about £80 vs the Specialita.
Ascaso Dream PID, Gaggia Classic Evo Pro
You want Eureka Mignon quality at the lowest price. If you weigh your output dose on a scale (which you should), the manual timer is perfectly adequate — you don't need the digital display. The £80 saving vs the Specialita buys you a bag of excellent beans.
