Precision Stepper motor????

Is there a precision stepper motor and programming hardware that i could program to go to a certain 1/50 of a turn. I would use it for a locker lock unlocker, 3 digit combo lock. What are my best options for cheap?? Thank you

If you want precision then you'll need to gear down whatever stepper motor you want to use. Then all you need is a motor controller and micro controller to run it all.
BTW is this for your school locker? Are you going to attach this to the outside of the locker? If so i doubt the school will allow it and someone would probably steel it.

No need for a stepper motor that simply complicates things.
