I am a huge Ayashi no Ceres fan (*drools over Tooya*), but of the manga. I haven't seen the anime yet, so I wouldn't be able to tell you if it's a good buy or not. From what I hear from other fans, though, the manga seems to be much better than the anime (not to mention it has the gorgeous Watase Yuu artwork), and I highly recommend it. The only drawback is that it is a very long series -- 14 volumes -- but you would be coming in at a very good time since the last volume is coming out this month. If you have about $150 plus tax, I think it's a great investment.
