Thank you all for your time and trouble. I have looked at the links provided and it would appear that for most of the items I need the traveloasis site is great. We are relocating for 5 years initially with a view to making it permanent subject to visas etc. I agree hairdryers are not a big problem - I have dual voltage of those anyway. It was more things like a sewing maching from my father, who is not longer alive, and a brand new vacuum cleaner - also a gift. I would also like to bring my bread maker and food mixer (wedding gifts). I think the transformers or 'step up' converters from Travel Oasis will cover these items. I would still be glad of some advice on the PAL to NSC system if anyone out there knows anything!
Thanks again,
Leonie
