Favourite series of mine are Nana, Paradise Kiss (Ai Yazawa ftw), Death Note (amazing at first though it got boring later on). I also enjoy reading Bleach, I've gone off the anime a bit. The animation is crap compared to the earlier episodes. Oh, and Fruits Basket is cute as hell.
I've read a few others but they're the series I've really stuck with. Hopefully I can get some inspiration for some new series from this thread.
