Are they really worth it? My grandma ALWAYS buys a Kitchen-Aid mixer for the women in our family....and I don't know if I want to register for one. I do bake on occasion, and just use a hand mixer without any issue. It seems like people talk about them like they're the cure to cancer or something-are they really worth the money or the counter space it's going to take up? We're going to be in an apartment for at least another year, so space will be limited.
