It's identical in design to any number for Makita, Dewalt, or other nicer brands (1k$ from Festool). The point was that it's not a 15K$ tool. It's a 200$ tool for a Dewalt. SMH my head. Yes of course you could buy a bench mount industrial one or something for lots of money.
The design is the same, but are the materials, manufacturing tolerances, and QA the same? That cheaper model is cheaper for a reason. While you're right that most people won't need the $15,000 industrial biscuit cutter, I'd hesitate to use the cheapest model on the shelf.
