Most people including myself will tell you the 1/2 HP Vertex is the best for it's price. Inovative is also a good spinner, but more costly than the Vertex. Many people complain about the Donkey Spinners vibrating. A few say the Donkey doesn't vibrate, but more will tell you they do. The Donkey has to be bolted down to something because if it's vibration whereas the Vertex can be set loosely on a counter top anywhere. The Donkey has a little bit higher speed than the Vertex, but the speed of the Vertex is plenty fast enough to do the job.

Hope this helps.

I've purchased a Vertex 1/2hp ball spinner about three weeks ago and it's been great so far.
