anyone own one? i bought the CIA professional series the other day. used it about 6 times and tonight, while trying to process mushy lentils, the motor started to smell like it was burning and made weird noises. i'm going to return it, obviously, because i know it's not normal (esp. for a mixer that costs hundreds of dollars!), but i want to know-- should i just return it, or exchange it for a new one? because i don't want to keep exchanging it for a new one only to keep having a defective motor. i know they have a 7 year warranty, but i don't want to go through the hassle. call me crazy, but i'd like a piece of equipment that actually works.
