Kitchen appliances are one of the few electric things that generally don't come in dual voltage (don't think I've ever come across any dual voltage kitchen appliances). Your best bet may be in (east) Asia (thinking Hong Kong, Taiwan, Japan and Singapore) or one of the countries that may have two voltage levels (e.g., Brazil) but since baking isn't that common (most kitchens for locals don't have ovens), what you'll find may be expensive.

Are you actually going to be using it for cooking in many countries?
