OT; a very good house would set you back 350.000 Euros; the average house price in BN and ML is similar around $350K AUD (just a guess by the way). Which is about half of 350.000 Euros... Sydney is a lot more expensive within an hours drive of work.
But, if I were looking for a change Eurocontrol would be right up there on my list; so what does that say?
The grass is always greener, but you need to have the cash factor very much considered when weighing up your options. It works out about 1/2 money here (or less), with a lower cost of living equation, but sadly not half of one.
