Hold on to that money.
I heard a lot of stuff about that place, some good, some bad. What it boils down to is if you only need the TR then it is good go for it, but is it to get a job, get hours or something like that stay away its a mess.
Go directly to Ryan air or with any other company that does the same deal but wth bonding or something like that. If you are going to pay that amount of money make sure it gets you somwhere (this can be hard). There are 100's out there who can fly a 737, what makes you different? Do you know somebody who can get you in the door. Then go for it, but if you don't think about it. They won't help you if you don't get the hours on top and face it its not cheap to start with. And to get the hour it sounds like you have to wait a while.
No hours=No Job
