After decades, a family heirloom is on it's last legs. Our old and cherished Sunbeam electric hand mixer (handed down from Grandma Hannah) is about to become history. Since I'm forced to purchase a new one, I suppose I would like it to be top of the line. Is Kitchenaid the way to go? Their full sized electric mixer has been a workhorse in our kitchen for years, and I would appreciate any thoughts or suggestions for a portable version.
