I've considered Vol. 1, but sohitmeng about the scan bugs me. Also, about half the book is artist comment and novel-type pages, which are hard for me to get interested in I'm not big into King of Fighters, so 3 didn't really catch my interest much though if they're still untranslated by the time I get through the others, then I don't see any reason not to finish off the series by doing 1 and 3.
