I have a Cuisinart that I really like. I use it mainly to grate big hunks of cheese! (Cheaper than buying it already grated and it freezes well grated.) I also use it to 'puree' tomatoes etc.
I have a Braun at the cottage - it is ok, but I much prefer the Cuisinart.
Maybe its cheaper to buy grated cheese than invest in a machine... but I do use it for other things sometimes!
