Our Kitchen Aid died a few months ago and we replaced it with a
Viking. It is a powerful mixer and will handle all large home-baked
bread recipes. Its dough hook is also more aggressive than KA's and
will quickly mix flour and liquid without using the beater first if
that's what the recipe calls for. The KA always seemed to create an
impenetrable sidewall of dry flour. The height of the beater and
dough hook are adjustable so you can set the gap between them and the
bowl to be very small. All of the standard attachments are
available. Rear castors make it easy to move around the counter.
The only drawbacks to the Viking so far are that it makes an awful
screeching noise when running and the beater and dough hook do not
lock in place with a detent so they occasionally rotate out the head
when scraping dough from them.
We also looked at the Magic Mill but it was just too big for home
baking. It really isn't designed to make small (3 cup) batches. The
Viking handles small batches fine.
