So it is physical copies? Well Deathnote and GTO are vastly different mangas, so it's hard to gauge what you'd like from that. That being said, here's some series I know are easy to purchase in the west.
Bakuman (Same creator as Death Note, but it's about two aspiring manga artists. Gets in-depth to the behind the scenes of creating manga)
Akira (World-wide classic)
Monster (Heavy mystery/drama, very good)
Tokyo Ghoul (Fighting border-shonen with a really good setting.)
One Punch Man (Vol 4 just got released in English. You should know what this is)
But read stuff online, see what you like, then sink the money into what's good so you can support the mangaka.
