Is there anywhere in the US I could get a super 360?
I’m not sure how you could get one, other than trading somebody who has one… I bought 50 last year as part of a mass order we organized over on iTopSpin.com. All sold fairly quickly, I have none to sell or trade 
If you are looking for something that plays like it… although it is much bigger the new Spintastics QS is pretty close.
