We purchased the Vitamix 750 several years ago and have been very happy with it except that I always felt like the 48 oz container was too large. With the addition of the 32 oz size, I am quite happy with the capability. The lid on this size seals much better than the 48 oz unit which is an advantage but I was also disappointed that the base is designed to fit within the rubber stops on the motor rather than outside as the original ones do.
