From the research I've done into airline selection and recruitment it seems that the most important thing to consider with flight training organisations (and this is perhaps the added value that enables org. such as CAE. CTC, FTE etc to set such high fees) is the connections they have established with airlines.
Many airlines have exclusive agreements with certain FTOs that allows them to hand pick graduates and therefore don't really consider people trained at other providers. These contracts simply don't exist at many other schools so just be a bit wary :-)
Best of luck!
