Before you sell these - assuming you can - check out transformers made for building sites. Big and ugly, but also relatively cheap. For example, an Artisan series mixer is 325 watts; allowing at least 10% for surge, you need a transformer that supports about 400 watts.
This bad boy (we have one that's similar) is rated for 3K watts, and is <£65: http://www.screwfix.com/p/portable-transformer-with-2-output-sockets-3kva/84144
We put the required plug for the transformer on a heavy duty US surge strip (miniscule cost), replacing the US 3-prong plug. Works a treat. DH uses all of his US tools and I use for a couple of my larger US appliances. Years back, we had 3 of these and used for tons of stuff. Not pretty, but far cheaper than replacing appliances.
If I wasn't in the north of England I would snap your hand off and grab these appliances :-)
