not so sure about that in the future.

I saw some of the prices in singapore for fk510, seems to be increasing.

PS4 will have an edge here, because sourced from thailand, logistics costs lower and also got ASEAN preferential tariff treatment.

Comparatively, fk510 come from japan, some more yen and usd strengthening against RM, future purchase got don't seem favourable. If want fk510, better get it sooner than later before subsequent newer batches that costs more starts to come in.
