Just make sure the geared stepper has METAL gears! If it has plastic gears inside, those wear quicker and when the motor gets stopped for some reason, by a blockage in for example the extruder, the plastic gears may damage.
I cannot confirm the motors for you since I am using Wantai stepper motors, so someone else should confirm :) I have no experience with Kysan, however I've seen them around on the machine a lot.
