Yeah, I always find that Del Rey's releases are always a cut above everything else. I don't mind paying an extra 2 dollars for quality.
The problem with Viz is that (imho) they go overboard with the sound effects. And has anyone else noticed that there's ALWAYS little paper shavings on the edges of the pages? Bugs me immensely.
Tokyopop goes underboard, by not translating a lot of the time.
