I think there is.. especially if used with longer lenses, because the speed is controlled by crystal, which is more accurate.

Also, if you are using processor to drive the stepper motor (via appropriate drivers of course), you can pre-program the motor speed such that you go not need anything more that basic barndoor mechanic.

Also, have a look at Sounstepper (at sourceforge), this app can do this (it is running on PC)
