Tesol for young learners - any suggestions?

I did my Trinity Tesol in Prague a few years ago. Now I want to do the Tesol for young learners thing. It seems that there is nowhere in Taiwan to get either the Trinity or Cambridge version. It’s a pity because they are the most widely recognized. Anyway, my question is this: Has anyone done a Tesol course here (especially the young learners one)? I may be interested in doing a course online, if that’s all that is available. Anyone done this recently? I heard about the American Tesol Institute( americantesol.com/ ) , but not sure if it’s any good. Help!
