Last Fall Cook's Illustrated published their results of their most recent ratings of blenders. Not surprisingly, an expensive Vitamix 5200 was ranked #1.

But the less expensive (but still expensive at $199) Breville shared the #1 rank.

From Cook's Illustrated, September 2012:

"The Hemisphere Control by Breville
With a curved jar, six well-configured blades, and a relatively powerful (750-watt) motor, this blender excelled at almost every task and at less than half the cost of our co-winner."

I bought a Kitchenaid 5 speed blender two years ago and have been happy with it so far. It does an OK job on ice.

I was just watching a commercial last night that was interesting.
Was for a "Ninja System", has a more powerful motor than the Vitamix (2HP), better blade design and only cost $160.00.
Also comes with 1 72oz pitcher a 64oz processor bowl, 2 single serve 16oz cups that you can blend in directly and a dough making blade.
Comes with a 5 year fix or replace in home warranty.
and a free 60 day tryout shipping paid both ways.

I bought a Cuisinart blender a couple years ago, it is basically a piece of crap and I would not recommend it.
