I think Agony you have to look at paying for an aircraft type rating such as a 330 as the thin end of the wedge. From an airline accountants point of view, why not make you pay for the 787 type-rating? You've demonstrated you can afford to pay the first time, so why not a second time?
This trend of paying for everything, and then being insulted with a derisory salary has found its way into the European job market, it has however stopped at the entry level positions because experienced crews wont stand for it. If you pay for the 330, be prepared to pay for the 787, and be prepared to reap what you sow in terms of salary and benefits.
(As an aside I practise what I preach, I recently turned down a job offer back home in NZ on the basis the company wanted me to pay for the type on my license)
