So I took a cheap mini drill from Ali Express added a motor controller, stripped out the transformer that had a Euro lead on it and added an NZ cord and plug and now I have a mini drill that goes really slow and the whole thing cost lest than $20

It's not really a score in the sense that I found something cheap, I bought the components with the intention of building a variable speed drill. Without the motor controller it runs at some insane speed but with the controller you can see it turning, it's that slow. It also has a fair amount of torque which is always good.
I have a feeling that I'm going to be building another one for someone else....... so I'll try to document the steps so anyone can do it.
