Although the points Dipper was making about objectives are very valid. For folks who want to recreate their home lifestyle and view HK as a hardship posting, a LOT of money is necessary to be happy. I think we can all point to a few (past and present) posters who appear to live in this category.
I had a great salary living in Kuala Lumpur and a fabulous flat (probably one of the biggest and nicest places I have ever lived). Company car, cost of living allowances, flights home, +++. Still hated the place and couldn't wait to leave and give up all those luxuries just to go to a "nice place".
