I'll be the lone voice of dissent here. VitaMix are the best, if you are looking for a bar blender. Personally, I don't like bar blenders. I think immersion blenders (a.k.a. "stick" blenders) are much more versitile, useful, and easy to clean. They are also smaller, if space is an issue, and less likely to sit on the counter, left plugged in all the time, as electricity vampires.
If you want an immersion blender, I'd go for the ($$$) professional Kitchen Aid. These are a fraction of the price of the VitaMix, but the most expensive immersion blenders I've seen. But even my low end Cuisinart does a fine job crushing ice and pureeing raw veggies.
Since our toaster oven died (we've been grilling bread rather than toasting it, and just let me say, I'm never going back- sooo tasty), we are down to five plug-in kitchen appliances: the immersion blender, the Kitchen Aid mixer, the Cuisinart food processor, the Crock Pot, and the dual sided grinder (spices/coffee). I'm planning on replacing the grinders with a moartar and pestle and a hand coffee mill. The Crock Pot I'll let go when we remodel our kitchen and get an oven that never goes cold.
But the Kitchen Aid, the Cuisinart, and the immersion blender? Those you will pry from my cold, dead hands.
