My old stand mixer just went out and I have 6 cake orders for this week. I need a Kitchenaid that is easy to use and reliable but also large enough to make large quantities of buttercream at a time. I was looking at the Artisian 5 quart but then noticed that there is a Kitchenaid professional 6 quart that has a lot more watts of power. It is $100 more than the Artisian. If it will work better and last longer I would be glad to pay more since I make from 5-7 cakes a week.
