Seeing as a number of you enjoy baking, I thought I'd solicit your advice on stand mixers. If you purchased a stand mixer, have you used it enough to justify the expense? Or do you think a hand mixer and bowl would have sufficed?

I like to bake (low carb) desserts (tarts, cakes, mousses, macarons), but don't make bread or pizza crust. I'm toying with idea of purchasing the Kitchen Aid mini stand mixer, but am aware that stand mixers often gather dust in people's homes. Have you used yours as often as you anticipated? Or do you consider it more of a luxury baking tool than a necessity?
