I love them all. I have a very large collections of "volume one"s so I can at least watch the first disk of any anime series I happen to be in the mood for. There are a few that rise above the rest though, I particularly like Slayers, Kenshin, Street Fighter, Vampire Hunter D, Ninja Scroll, Kalidostage (spelling?), Samurai 7, Ranma 1/2, Tenchi Muyo, Scrapped Princess, Battle Athletes, Chobits, Revolutionary Girl Utena, Inu Yasha... Gosh, see what happens when I try to list out a name of my favorites, I can't stop. I'm not good at listing favorites of anything actually, everything has its place and a reason of its own to be respected and admired. Basically, I buy volume one of every anime series that I can find cheap online ($5-$10) and then the ones I really like I rent the rest of the series on Netflix. I just finished Maburaho (actually own the boxed set for this) and am working on season 4 of Ranma 1/2. Samurai 7 is on my netflix right now, but I've been too busy watching "volume one"s lately. The last "volume 1" that I finished is Strawberry Eggs.
