question for UK/Euro synth owners

I seem likely to be moving back to Europe next month, and the move is forcing me to think about a couple of issues. I've been planning to pick up a synth for a while. But quality musical equipment in the country I'm moving to is ridiculously expensive, and there's not much of a used market either. So while buying in the US would be best in terms of price and selection, I'd then have an instrument with the wrong voltage and power cord. (Unless synths nowadays are built to handle all currents, like laptops? Maybe that should be my first question.)

I'm guessing my next best bet in terms of price/selection would be the UK. I know the physical plugs are different, but are there any currency/voltage issues between there and Europe? Or am I better off trying to buy somewhere in Europe, just so I know there will be no worries? Thanks!
