Here is a good resource as well:

I also do not know the spec of the current motor, but a 0.9 stepper is a good idea.  Between that and the smaller pitch diameter of the Hobbed Goblin you will get much higher precision.

Tried drilling it out, but it's a real pig. So I might just get a replacement.

My first thought is this:

I also found this locally

But that might be a bit heavy for already overworked X carriage stepper.

Any thoughts? What would you choose? Does anyone have the specs for the Extruder Stepper for an SD2?
