Wizzair is mainly sending people to Airbus in Toulouse for the type, not exactly the last ato in europe.
You can either pay about 14000 eur upfront, or be bonded for 420 a month for three years. And if you stay 3 years you get back 7500 eur.
Nothing like pay to fly, actually one of the best arrangements in europe for type ratings, much better than let's say easyjet, that is/was charging 2,5 times as much, with no possibility of bonding.
