I'm going to go ahead and vouch for my new smootihe2go as well. I've only had it a week, not so ironically the same amount of time I've been on Exante, but it's amazing. It specifies ice crushing abilities, the cups have measure lines to show you how much ice to add and the cups have handy travel lids (for the dieter on the go).
My only drawback is that it's a bit loud but what's a little noise between friends?
(Seriously for how thick and ice cream like you can make your shakes in this blender I wouldn't mind if it woke up the neighbours)
