It really depends on the terms though, I know a few years back it was still a "pay your own rating" kinda thing with them. No way in hell should you be paying your own rating for an E135/145, it's not very likely you'll use it anywhere else after BMI if you know how many are flying around Europe.
If they offer it with a bond and the terms are decent, go for it. I honestly think everyone should still go through the ladder from small to big. The experience will pay off later.
