It's not the best way to train, that's debatable.
You are not financially better off than a normal course, as long as you're willing to wait around and apply your tits off until you find a job.
50 000€ gross (in Belgium!!) over 3 years, working only 8-9 months a year, is a

The good thing is the guaranteed job and (hopefully, but unlikely as they're mostly short on E-jet crew) a 737 TR/hrs.
