Welcome Zvezda,
You may find that some locales have differing aircraft operating costs, and that's worth researching, if the travel costs become justified. Otherwise, shopping for the cheapest in training is not always the best plan. The quality of your training, is your flight, and maybe life safety. A cost reduction strategy can be to share the ownership cost of the aircraft. In particular, that provides you with a continuing lower cost aircraft after you earn your PPL.
