I love my 'vintage' Braun, which hasn't been made for eons. One of the things I love about it is that the bell rarely traps any air - it is shaped much like the one artemis linked above. I have an older Cuisinart that I do like, and especially like having the low/high speed option. I can tell you that I hated a Kitchen Aid I bought because I had coupons and it was on sale, and it was a cute color (I think I paid $11.00) for it. It was awful for soap, but is fine in the kitchen. Not much help, I'm afraid.
