skyeuropecapt,
thank you very much for your kind answer.
What you said might be truth, but there are some outfits which give hotel room or acommodation allowance. I admit, these are mostly non-european.
Also, if one does not have a job, than it's like you said: join and wait for better. But, if you want to move from one job to another, it's good to know if it's worth it.
