I would also advise with a rating you pay for what you get.
Most of the american or Canadian type rating are VERY bare bones.
Im working with alot of people who did ratings all over the world. Seems all the guys that went the cheap option. Regret it as soon as they start company training. realize how little they were taught.
I would also like to mention, if you do a less quality type rating, You may also struggle to pass a sim check on a interview, and then you have wasted alot of cash.
I would do it somewhere known to be good. As mentioned. Ansett, Air NZ, CAE, Aleton.
Good luck
