This is the one suggested by Consumer Reports for the best value. I bought it for my daughter, but it's in the closet for her birthday or Christmas so I haven't used it. Read the reviews - they're mixed. Don't know how long it will last reading the reviews, but it sounds like it is perfect for crushing ice and making smoothies in a creamy texture. After researching a lot of different brands I chose this one.
