I don't have hands on experience with either blender, but I do have with the Vita-Prep which is the commercial; version of the Vitamix 7500. The Vita-Prep is $40 cheaper than the Vitamix 7500. Both have the same basic features and look more or less the same on the surface, but the Vita-Prep has a bigger motor designed for the rigors of a professional kitchen. I have never encountered another blender that I even remotely like as much. The Vita-Prep also is designed for long life as well as for the rigors of professional kitchen life. I have had mine for probably 25 years.
