Truthmaster,
The practice of purchasing type ratings is quite common in many countries. Even the United States has a very large "famous" airline that requires all new pilots to pay for their type ratings.
I myself would rather get paid to get a type, as opposed to paying for it, but it is a way to look attractive to some airlines, where a type is necessary. The problem with most Asian carriers (Cathay and Dragonair excluded) is that they require significant time in type.
Good Luck,
Do what YOU feel is right.
Cheers,
