I've done this a few times. See a discussion of issues you will face in
my chapter "Living in Europe: Travel to the Max as an Expatriate" at
http://www.enjoy-europe.com/hte/chap22/living.htm

Interesting read, to see how European things are viewed from "the other
side". However, I'm wondering how long ago this was written? Some things,
such as "Because credit cards are expensive, few Europeans use them" are
simply no longer true.
