BOAS has always liked them mangas but it's hard to decide which ones are good nowadays at least in the US market. Good thing there're monthly magazines that give you a good range of manga and anime.
NewType: Expensive! Included DVD? Whatever, skip.
Shonen Jump: Have been a suscriber for a while. Well worth the $30 per year. Included are Naruto, Hikaru no Go, and One Piece.
Shoujo Beat: I just caught a glimpse of this at a local manga store the-other-day and man is this good. With titles like Nana and Absolute Boyfriend this is great for the girls and guys ;_; A little more expensive than Shonen Jump though at $35 USD per year.
