Came across these stepper motors and drivers on eBay:

and

I'm not going to need the drivers, but the steppers look tempting. They're marginally lower inductance than my 3Nm motors (and the 3nm ones he sells), yet higher torque.

Would be interested to know if anyone here has used them - wondering if it's too good to be true!
