You'll still need
- Check with the maker whether a spindle is included; the page doesn't say.

Work area to scale
Features
Spindle or router
Not stated on the pages I read. The spec page says it "Supports both 65mm and 80mm spindles and routers. For 80mm spindles, cutting area will be reduced."
Size
Cutting area 49″ x 32″ x 5.1″ (spec page). The 5.1″ is the Z of the cutting area; this page gives no separate clearance figure, while the 30x30 entry uses the 4.6″ clearance from its product page, so the two Z figures aren't like for like. Millimetres converted by me.
