I'm going to bet that the overall construction of the Cyclone is better than the Cyclone II. They are trying to make things cheaper now. Does the table your looking at have the solid wood corners? The Cyclone II has the plastic down corners, and the plastic caps at all 4 corners. (Which if bumped hard enough come off) I know......cause I have a Cyclone II. I got a scratch and dent Cyclone II with a very badly damaged down corner, and cap. I did manage to repair it, but when I was looking at the overall construction of the cabinet as I was repairing it, I wasn't very impressed with Tornados quality. Don't get me wrong. I wouldn't trade the table for anything. It plays great, and I am very happy with it. It just seems like if this is the best table in the world, you would think they would be put together with more than just glue and staples.... I'm sure you will be happy with either table. Find out if it has counter balanced men, the larger diameter rods, and the split bearings. Thats really all that matters. The Cyclone probably has solid wood legs as well. The Cyclone II has solid 4x4 plastic or pvc legs.... Which is probably cheaper to manufacture, and less prone to warp if near humidity.
Hope this helps. If you have any more questions feel free to ask.....
