I'm a baker and in the bakeries I've worked in, the mainstay appliance is Viking, but some of the smaller appliances used in some of the smaller bakeries I worked in were Kitchenaid.
I can confirm that Kitchenaid mixers are ****** made to sell at price-gouging amounts. One mixer I used was brand new, the bakery just bought it, and after the second use of using it, the lift handle for the bowl stripped! We couldn't get the bowl lowered again. Another KA mixer at another bakery I worked at, the gears stripped out and we couldn't get it to change speeds anymore. All in all, I think I use probably around a dozen different KA mixers and each one of them were pure ******. Most of the bakeries that used these threw them out for other brands, which we never had any problems with.
My favorite mixer brand is Sunbeam. I even bought a Sunbeam stand mixer for myself. Iv'e been using it for years and have NEVER, EVER had any problems with it! And on top of that, it's like a 1/4 of the price of those Kitchenaid mixers.
If you are going to invest in something decent, get something else, don't get Kitchenaid. I've found that Sunbeam, Cuisineart, and Hamilton Beach make better products that Kitchenaid.
