I myself am a flight instructor in the USA and currently here in the Philippines applying. My best advice, and again this is my honest opinion, is try to get your training in the USA. It offers some of the most advance equipment in the General Aviation arena and you will be trained not only in the best flight enviorment in the world but you will be trained to be the best.
I'll admit, that the cost maybe expensive for some, but I have met many Filipinos at ATO who did their training in the USA and said they were quite pleased with the training. Also, the conversion of your FAA to ATO would be a piece of cake. They know the training in the US and have no problems of validating it, just remember to be humble in the office or your validation will be more difficult than appying for a student pilot certificate.
