Oh, yes. I love the Yu Yu Hakusho manga, as well. ^^ I like it better than the anime to an extent, because it showed stories that was never in the animation. I've read up to volume 12 (didn't get 13 yet! DX). Overall, I really like it, and I've been into YYH since I was eleven. I started out watching the anime and then I got to reading Shonen Jump.
HunterXHunter is something I'd really love to see. Just need to get my hands on it eventually. XD;
