Budget: Under $1,000

Under $1,000 covers the live desktop CNC shortlist: compact 500W, 400 mm 300W, and the 400 mm 500W ACMER pack. Large-format sheet routers sit well above this band.
ASCARVA 3S for compact 500W carves, VEVOR S4040 for live 400 mm 300W panels, and ASCARVA 4S when 400 mm plus 500W is worth a preorder wait.
Buy 3S when parts are small and spindle power matters. Buy S4040 when 400 mm jobs start this week. Buy 4S only when that envelope is already paid and the ship window fits.
Stretch when rigidity, automatic tool changing, or sheet-scale travel is already a paid constraint. Do not buy a larger frame to feel production-ready while weekly blanks still fit a desktop cell.

Stay inside the band only if the machine plus shipping, exhaust, software, and a first load of materials still fit. Use the cost calculator so payback is not computed from sticker price.
Sticker price is not the investment. Model shipping, setup, and first-year cost in this band.
The shortlist above is curated. The category hub has the rest of the catalog, filters, and other research landings.
No. This band is desktop and benchtop routers. Full-sheet machines are a different capital class.
Yes. Bits, workholding, dust collection, and CAM belong in the cell budget—not as afterthoughts.
