Hey guys and gals I recently learned about the manga called Buddha by tezuka and I wanted to buy it. When I look on Amazon thought I find one copy of the volumes by vertical in hardcover and another one a box set which has all of them together by I think Harper something. Is there a difference between these two publications? Is the translation different for one and does does it matter which I get? I would rather get the box set which takes less room in the apartment I live. Thanks!
