Ascaso
US$1,699–1,749 · CA$2,195–2,735
The Steel Duo PID trades boiler mass for thermoblock speed: you get concurrent brew-and-steam and near-instant recovery in a genuinely compact package. Accept that a vibratory pump and therm…

Quick Mill
US$1,200–1,600
The Luna delivers dual-thermoblock convenience and simultaneous brew-and-steam at a price well below comparably specced dual-boiler rivals. Buyers must accept that shot-to-shot temperature c…

The counter’s vote
Looks barely figure in either machine’s record — the counter can sit this one out.
Luna: Minimalist stainless steel with engraved icons—appliance-neutral, not a purchase driver; elegant but not talked about as a design selling point
Only the Steel Duo PID: the standard 58mm ecosystem.
Only the Steel Duo PID: no accessory lock-in.
Where they tie: milk & steam · shot ceiling · back-to-back drinks · forgiving to learn on · parts & repair — don’t let a spec sheet invent a difference.
On the counter
The size difference, to scale
So — which one?
Take the Steel Duo PID if —
- Patience is not your virtue at 6 a.m.
- It has to just work, every day
- You want a button, not a ritual
- Every dollar has to earn its place
Take the Luna if —
- The difference stays in your pocket — or goes into beans
- There are sleepers to protect
Both columns reading true? Take the Luna and put the difference into fresh, roast-dated beans — they move the cup more than this choice will.
Known weak points
Luna
Temperature instability on early shots and cold starts; PID display fluctuations; weak steam heating (80+ seconds for milk); volumetric programming unreliable due to resistance variance
