after our hand-mixer puked about 12 years ago, i decided we needed a counter-top mixer (because i wanted to start baking). my wife went out anyway and purchased a hand mixer because she is afraid to use my counter-top, eh, eh, eh. i am really anal with my stuff--to the point i still put the cover on the plug and wrap the cord each time.
the machine is really versatile and generally comes with several tools. the bread hook enables you to knead bread dough and the whisk attachment is great for making whipped cream or meringue.
after this peach cheesecake is gone, i'm going to make a chocolate key lime pie. that would much harder on the wrists using a hand mixer.
if you really like to bake, spend the money and get a good counter-top. you won't regret it.
