One of my recent debates has been whether or not I bring my KitchenAid mixer and food processor with me to the UK and buy a step-down power transformer. The transformer converts the 220v to 110v, but European wattage runs at different cycles than US appliances. Using the power of the internet, I've found just as many "it works great for us" stories as I'm seeing "we tried it and it blew out the motor of our mixer" ones.
I've discovered Craigslist for London, but don't see any for sale right now (although it could be a great place to dispose of a 220v one before I leave?).
Are there any electrical engineers in da house?? And no, as much as I try to save electricity, a wooden spoon and a hand-whisk is *not* a viable alternative. I do knead my own bread, but hand whipping 2 cups of heavy cream is not the workout I'd choose.
