My advice stay away from those kinds of schools, the cheapest and most afordable is ATP- Airline Transport Professionals. They give you the price that you will pay, and not a cent more. Unlike most of the schools at your local FBO, ATP keeps its word about the price of trainning.
Those schools in Russia might be cheaper, but the flight training quality is poor.
Their millitary flight training is great, but when it comes to civil it just sucks...
