I LOVE my Bosch. There are a couple models. I prefer the one with the "center tube" because it is such a wonderful dough hook. It will knead several loaves at one time. My MIL has the one without the "center tube" which is much smaller and it didn't stand up to time as well (we've had ours since 1987 and they have updated the look but the basic machine is the same). There are a couple new models that look interesting (motor size is everything) but I really don't want to build one into my cabinet.
These are just a couple places to find Bosch mixers.
