Anything that has an AC motor with any power is not going to have a dual-voltage equivalent--the resulting device would be heavy, inefficient, and expensive.
In the garage, I use a lot of rechargeable or DC-powered tools with dual-voltage transformers, but those aren't so common in the kitchen.
My vote is just to buy a cheap hand mixer on your trip to the Netherlands and hang on to it for future travels to 230V countries. Amazon.de has them starting at €15.
