It's right that at the end of the day its us who have to pay for the TR but in my view that one should better wait for sometime now or even if they are willing to do the TR then they should only opt for those TRTO's which the airlines send their own candidates to....viz CAE, or one in London/Gatwick etc.....
I personally know some guys who have have gone to "not so renowned" TRTO's and now facing the music from airlines....they have done their TR from countries like Luthinia, Hungary and even South Africa....and they tried to appear in the Jet exam for T-rated pilots and were not allowed to do so.
