What stepper motor do I need?

Ok I have a lulzbot mini with a flexystruder head. I would like to hijack the stepper motor off it for another project and buy it a new one… Which of the steppers in the store are the right ones? There are 3 that I see. nema 17 for $6.98, nema 17 with moons for $22 and a half height for $12.95


I would recommend this motor : https://www.lulzbot.com/store/parts/nema-17-stepper-motor-moons-including-adapter

You could also use the : https://www.lulzbot.com/store/parts/nema-17-stepper-motor

The first one is a much better quality motor and comes with the connectors. The second will need to be wired to the toolhead.
