Are there good but affordable international schools in Manila?

There are a good amount of international schools in the metro. I can't attest to the price of each and every one, and I can imagine they get rather expensive. In any case, I found the definitive list of all of the schools. Perhaps you can do research based on which area you prefer and go from there.
