I found mine by using an app on my smartphone which gave me a notification any time a Tornado came up in a predefined search area. They were mostly home models, but every once in a while a coin-op would pop up.
I was quick to respond and got the table. The guy who sold it to me said he had 8 would-be purchasers by 8am the next morning!
As far as differences are concerned, I can tell you right off the bat that the men are very different. It looks like the Garlando men employ a shorter, smaller, squared foot. These are useful for a variety of shots (back-pins, banks, etc...). It's more of an old-school style. To me, the squared feet yield a more frantic playstyle. The ball is harder to control. It may just be due to lack of experience, however.
The Tornado men have a long, wide, pointed foot which seems to grant more a supple control over the ball as well as the famed Snake Shot.
I think the main benefit to buying a Tornado in the U.S.A. is that they are very common amongst foos enthusiasts - thus allowing you to use your specific skillset outside of your home.
