I know they say you should support the Mangaka by buying the manga when it's available in your region. But the fact of the matter is that the mangaka hardly sees any income from sales in other countries. The only thing a licensor in the US usually pays is just the fees to the original publishing company in Japan, and this primarily because it's all on the licensor to do everything a scanslation group does, as well as market, print, and distribute the manga.
Sorry, but I'd much rather just buy the original titles in Japanese and run them through something like Sugoi Manga OCR. The Mangaka will get a lot more of my hard-earned dollar that way.
