ok so finnally i am going to be adding a shuttle pro to my machine . but I am not sure what is the difference or even which is the right one to buy ,
I am looking on ebay and they all look the same       (are they all the same?)
can someone tell me which is the right one to buy.
and also what do I have to look out for. so I can buy the right one to fit MACH,S  DOWNLOAD.
thanks

It's the black one that says "Shuttle Pro 2" . I would not attempt to buy the older silver one as I don't think that one is compatible.
