All the following are the same machine, with different logos on them (for instance the CIA professional model says "Culinary Institute of America" on it)
5200 CIA™ Professional Series® Creations® II Creations® GC Professional Series® 200 Total Nutrition Center® TurboBlend® VS
The only difference for these are vanity logos printed on the motor housing, electronically and mechanically they are all the same. For instance the Vitamix Professional 200 is the vanity edition of the 5200 sold by Williams-Sonoma, but the machine is actually the 5200. They're all the same.
