Ya know, I was drooling over that list of features in the Elite... right up until I got to the last one. That honestly kills it for me. But I will say that the 3 different bowls would be really nice, as would the blade lock - I hate that particular fact of life with my KA.
I have the one that was linked above, and I've been perfectly happy with it. Got it as a wedding present. I may not use it as much as I used to - but that's just life with a toddler (less complex cooking). I use the small bowl much more often than the big one - sauces and marinades and the like do nicely in there. I will say though that it can't handle making mustard from seeds... I was very disappointed, next time I'll try the blender.
