I did mine in the UK a few years ago and I was rather lucky to receive very good instruction in all areas. Initial training is important but in any case you will have to do a lot of studying/work yourself anyway. Even if you don't end up completing a brilliant FI course, if you have the passion for training, dedication and commitment, you will get there. It is hard work and quite underpaid everywhere but I think it is very enjoyable and fulfilling. I have worked with new FIs who were not lucky in their training and they got to be excellent FIs at the end. On the other hand I have worked with elite school graduates that had no interest in what they were doing and in the long run they under performed. I would suggest you to visit a flight school and if they people look alright, and they have the materials (briefing, notes etc) go for it. best of luck!
