Hi! If you are considering schools in India, then i would recommend:
1) Chimes Aviation Academy - could be a little pricey though. Otherwise they have a modern glass cockpit fleet and good training standards.
2) IGRUA - very good training but you need to find out if they accept foreign nationals. Modern glass cockpit fleet.
3) Madhya Pradesh Flying Club(Bhopal) - Cheap and quick training.
Cost of living is much lower in India than other countries so even if your training gets delayed due to weather or maintenance issues, you won't loose much. Generally the weather in India is predictable and conducive for flight training except for the monsoon season(June-Aug). So you can plan to have theory classes in these months and conduct flight training during other months.
The Indian aviation regulatory authority is DGCA(Directorate General of Civil Aviation). DGCA licensing exams are known to be a little tough so i would suggest that if you train in India then you start studying before coming or come earlier than when your flight training starts and take ground classes here itself. Cost effective ground classes are available at many places.

Good Luck buddy!
