How old are you ? Early 20s = go for it, mid 40s = think very hard.
How is your present job ? Company/Location/Lifestyle
A 25 year old with a young family working for a crap low cost in the Middle East or Europe with an unhappy wife and poor job security would be mad not to take ANZ.
A 45 year old with a nice job in a good location would have to consider very carefully.
I assume you are somewhere in the middle.
