I never used motors before, I need a lower than 0.092° step on my motors, at first I was looking at stepper motor but then I learned that you can loose steps and that closed loop stepper motor are better.

To get that accuracy I will maybe need to use a gearbox.

So I found this motor 
Closed loop, 0.057° per step, PERFECT.

But it's 260$ and I need 2 of them.

Do anyone know where I could find dirt cheap closed loop stepper motor? I looked everywhere on the internet and the minimum seems to be 100$


ps : check my projects page to see the current turret.
