I saw one in Runner's World that is designed to make a single serving smoothie and is designed to be an all in one type deal (i.e. the pitcher is the glass when you are finished blending). Don't remember the name but I will look it up when I get home.
The one I'd get is the Magic Bullet Blender but that wll have to be on my Christmas list. Here's a link to one at Walgreens for $60, I think other stores sell this for $80.
