I have a Vita-Mix, which is the granddaddy of hardcore commercial grade blenders sold to home kitchens. The thing can boil soup if left at top speed for five minutes. I'm bragging. About my blender. Because owning a Fuck You Grade blender is exactly as fun as the videos make it look.
I want a back-up container for blending the seriously inedible, but I think I would cry if I did manage to hurt the motor. No. I know I would cry.
I've got an old, 60s commercial grade Waring that was used in a lab to break up small rocks years ago and still works well. And yess, it's very satisfying to have a good blender.
I have owned 4 blenders. the first was a cheapo during college and I do not remember it. The second was a model that broke within 6 months. the third was another model that broke within a year. the fourth is a Kitchen Aid from the 80s that cost from the Goodwill. It has one setting, and at this setting it will liquify a whole chicken thigh, bone and all, in under a minute I shit you not.
Update: I eventually went with a 0 Ninja blender. It chops ice into snow, it makes smoothies, and I'm sure it does other useful things too.
For me the Ninja is the proper price point: less than 0 and you don't get the functionality (such as being able to chop a frozen strawberry into a paste), but a Blendtec or Vitamix is probably overkill and four times the price.
