Eh, I would buy a Japanese manga if it was really cheep to be honest. My friend bought a Claymore manga in Japanese from a Goodwill (Thrift store) for 75 Cents not to long ago.
As for that MegaMan comment. Yeah, I'm lucky that MegaMan is still around. However it's not like the orginal MegaMan or even the X series are still going. Mostly it's that Battle Network/Star Force stuff now. Which I rather dislike. (Except the Star Force anime. That's awsome! Though I've only seen it fansubbed not dubbed)
I'm lucky the ZX series retains what I love about MegaMan, and just have to hope it keeps going.
As for reading Dragon Half scanlated. I'd just go here:
