I have volumes 1 and 2 of Bakuman, volumes 1to4 of Kenshin's Kanzenban, volumes 1to17 of Fullmetal Alchemist, volumes 1to3 of Saint Seiya's Kanzenban and all 10 of hellsing, that I want to sell as I didn't enjoy it as much, and I only bought it because it was a complete series, and I wanted to feel how it was to read a series first in physical form.
I want to buy mostly the Kanzenban of series that I like, but other than Dragon Ball, Kenshin and Saint Seiya, there's not much spanish Kanzenbans, only Monster, Dr Slump and some versions of Ranma 1/2.
Well other than the 3 up there (and the very real posibility of finaly reading Dr Slump) the only finished Kanzenban that I'm interested is Houshin Engi. And Maybe Yu Yu Hakusho (that I should check again if there's an editorial that's printing it in spanish)
