The keyword might be: it depends.
I'm not sure if some of the posters above just give you that advice because they don't want another competitor in the market. They had also to go the long way up, aren't they?
Well, they might be right. On the other hand, if you have to opportunity, the possibility and the prospect, you might want to do it. But it depends on where you are, what you are and what you make out of it.
I have to agree that it is very difficult to get a good job with few hours on turboprops. You need to have a few 100 hrs on type. But there are jobs out there where you don't need it, especially in Asia.
The only advice I can give you: Look around and keep checking the possabilities. Distribute your CV to everyone and check the schools that offer you courses and training. Check them well! Be smart and use every hour as a training for your future career.
Good luck,
Dani
