search the threads around here...there is one thread called IngiGo and the Pay-for-Play Wannabes/SOs.
Do NOT go to simcenter/ICPilot. At least go to CAE, who is at least mentioned on IndiGo's website.
I would only do CAE, and even then I would be very very wary, because rumours abound of CAE losing that contract sometime soon. If they lose the contract whilst you're in training, and IndiGo switches to another TR provider, do you think they'll give you your money back? If so, go for it...if not, I would stay away.
Then again, aviation is much like gambling...you can go "all-in" and get a job on a jet with low time...or lose all your money and go back to a regional/charter job with a $12-30K hole in your pocketbook that is pretty tough to fill with a regional salary.
