I just got back from a month long stay in Germany. Before leaving with my Janome 3160(which I bought specifically for a travel machine) we looked online and found that the Janome's are made for world power. So all you need it an adapter and you are good to go.
So look online to see that whatever you buy will work in different countries. It was great to sew overseas, but be aware to take all the fabric you need as fabric in Europe is quite expensive. There are not big discount sewing stores so take all the thread, batting, trim that you need.
Happy sewing.
