According to your budget this probably isn't helpful , but John Lewis, House of Fraser and Debenhems all list Kitchenaid mixers at £389. Finding a new one for £180 in the UK seems optimistic. I am certainly no expert on this, but what you have to be careful with buying US appliances to use in the UK is the voltage. US appliances are 110V, I think and UK are 220V. Even with a converter you will risk the appliance not running correctly, overheating, etc.
