I need serious workhorse of a mixer for home use to make bread.

-------- STORY of my OLD mixer
At least six years ago, I purchased a KSM100 mixer. I loved that
thing. Many people recommended it because they said the newer
Kitchenaid mixers had a hard plastic gear, but the Kenmore's still had
a steel gear and could take heavier doughs better. I found one on
sale, and loved it.

I used it to run a little side-business out of my home baking bread.
I worked second shift, but I would get up at the crack of dawn, and
every Monday, Wednesday, and Friday for a year, that mixer churned out
anywhere from three up to nine batches of dough (was just over a two
pound loaf in each batch). The bread business died off, but I still
used the mixer for home use constantly.

Sadly, two Christmases ago, my mixer gave up the ghost. I've been a
lost (baker)man ever since.
---------- END STORY

For Easter this year, I borrowed my mother-in-law's Kitchenaid to make
our traditional bread. I forgot how much I missed the smell of yeast
and flour in the air, but I could tell that her mixer was struggling
with my batch size. It didn't have the umph of my old KSM for sure.

Our income tax returns came in over the weekend, and a mixer is my
"gift to me". Not having seen what's on the market, I want to know
what I should go out to buy. I know wattage is important (the 600w of
the KSM was often put up against the 525w of available Kitchenaids of
the day), as well as bowl capacity, speed settings, etc. At this
point, I am even considering hitting the local restaurant supply store
and snagging a decent table top Hobart (yeah, I'm that crazy about my
bread mixer).

Help appreciated in advance.
