You know the other option is this, in Europe 220v is common with one major exception - power hand tools like corded drills and saws. They're still 110v. I used to live in Dublin Eire and had some construction workers for room mates for a time. They would have to carry a small transformer with them to the job site for their power tools. I asked them about it and they said this was common for small tools to be 110v because of the American market. Here is an example from ebay - http://cgi.ebay.co.uk/110V-Power-Tool-Transformer-3-3kVA-Extension-...
Only about $60. Way less then the potential hassle of finding and changing an element. Probably can find one in Switzerland when you get there.
For those interested. I ended up buying a whopping 3000W transformer. I wanted to be able to power my american grinder at the same time. It was 144 euro and weighs quite a bit, but now I more or less have an american wall outlet in my kitchen. So far I have had 0 problems.
