I agree, with Caroline, either Brother or Janome are good makes. Yes the electricity is 240v.against 110v in USA.
So shop Amazon UK. The delivery address needs to be in UK and you can use your US addess for
billing purposes.
Your daughter-in-law is a lucky lady indeed, to have you for a mother-in-law.
Good luck and hope all works out for you both.
