Motorizing a Walther's HO scale oil pumpjack (Horsehead)

Have any of you folks built and put the optional motor/gearbox Walther’s sells on it to make it a real operating “walking beam” pumpjack? Is it as cool as it would seem to be? They sell a completely assembled pump, motor, and gearbox for O-Scale and they look pretty impressive. I’m hoping the smaller size does too.

Thanks for any responses…
