The VitaMix unit. Old model. Don't let the size fool you. This unit is as loud as an outboard motor and has a destructive capacity that has to be seen to be believed. If any of you saw one of their tv commericals decades ago, they showed someone dropping in a few wooden blocks into the mixer, turned it on for a few seconds and producing a nice, tidy pile of sawdust. Trust me when I say this unit is capable of such an act. I have not been to the company's Web site lately, but expect the price to be well over $300.00.
