Verdict
TL;DR	Acmer S2 Pro 36W is the lower-power SKU on Acmer's S2 Pro line with rotary and IR bundle options. Compare to S2 Pro 48W before buying: often worth the step up.	Acmer S2 Pro 48W is Acmer's high-power open-frame option before the enclosed P3. Strong cutting claims: verify optical power and compare to P3 48W enclosed if you need smoke control.
Pros	Built-in 30 L/min air pump: cutting setups need no separate compressor Basic pack at $582 on Acmer's store (October 2026), about $178 below the 48W Same 400 × 400 mm bed, 0.08 × 0.1 mm spot and 24,000 mm/min top engraving speed as the 48W	Widest cut range of the S2 Pro line in our profile: basswood up to 10 mm and dark acrylic up to 5 mm Fastest fills of the line: ~12–18 min for our 10 × 10 cm photo test Built-in 30 L/min air pump, so the extra power translates into cleaner cuts without add-ons
Cons	Acmer publishes no cutting chart for the S2 Pro: our benchmark puts a 10 × 10 cm square in 3 mm basswood at ~7–12 min, slower than the 48W Real fill speeds sit far below the 24,000 mm/min headline (~29–74 mm/s in our tests) Rotary, camera and IR packs push the price to $686–1,227; the IR pack alone adds about $477	$759.99 for the basic pack vs $582 for the 36W, and up to $1,404.99 for the All in One pack (October 2026) Same 0.08 × 0.1 mm spot spec as the 36W: no gain in detail, and more smoke at full power Open frame: if smoke control matters, compare Acmer's enclosed P3 before buying

“Best” highlights the strongest spec on paper for that row only — not an overall buying recommendation.
