The chance of frying the stepper drivers?

I once managed to fry the motor driver on the V3 Extruder broad (when I used it on a gearhead DC, maybe back EMF or alike killed it).

Maybe I was just having bad luck. In general, is stepper driver stable and long-lasting? I am shipping shopping for electronics set, not sure if I should go with pololu-alike design or integrated one.

They are generally quite reliable. Unplugging (or plugging in) a motor while the driver is energized can kill it though. I've haven't had one die in the past three years.
