I think you're going to have difficulty finding a better option than the Faller. If it's AC, it has to fall within an appropriate operating voltage and also have slow enough rpm. The DC motors can be used if you rectify the voltage etc., but then you're usually dealing with very high rpm. Look around on the Internet and you'll find them below 30 bucks. You will have to "play" with it a bit to get the armature of the motor to attach to the shaft on the end on the dish, but it works great.
