I was an expat in France for a couple of years. I paid both U.S. and French taxes and it was (and years later is still) a huge headache. Earlier this year I finally put my 1999 taxes to bed.

As for SIN, I have some Aussie expat friends there who love it. It's a short flight to plenty of great destinations from SIN and as we all know SQ is a fairly decent airline. You just have to make sure your package includes vehicle taxes. They are extremely prohibitive in SIN.
