only ones on this list I've seen are:
High School of the Dead : only watched the first episode when my friend came round, seemed quite good if a bit messed up
K-On : same as above, but not quite as messed up, will watch this through soon
Love Hina : it's good but I found it got a bit hard-going near the end, haven't bothered with the OVAs and extras as my intrest was nearly gone by the end of the main series, however, I found Negima (by the same guy) to be awesome from start to finish
