Unfortunately I can't say with confidence; mine is one of the servo-controlled ones that cost exactly $1K (new). I don't have first-hand experience with the stepper-driven ones. I will say, however, that 3D printers in the sub-$5000 space are pretty much all steppers, and those work great, so I doubt a stepper vinyl cutter would have positioning problems. The forces involved aren't high enough to make the drive system miss steps, skip belt teeth, etc..
