The 6300 is the fancier one Costco offers when Vitamix is doing a show. The DVD that comes with is using the professional model (not sure which one). The only difference between the two is the housing is more plastic like while the pro is all metal housing.

6300 has the tall container which fits in my kitchen, but our cabinets are mounted higher than standard. I wanted ample room for the epresso machine at the time I mounted them.
