The advantage of the motor I bought is, it's quiet! I can't really hardly hear it run. Not even a slight hummmm. The base price was $11.95 I think. You can find them probably cheaper, which I did on one, but they wanted about $9 for shipping, so I kept searching. It is a "Mirror Ball Motor" for you old guys that remember "DISCO" fever and such...... I just need to add a switch now.
