Pani Poni Dash
School Rumble Season 1
School Rumble Season 2
All good shows that i'd recommend a good deal. You'll have a good time with these.
As for Slayers, i tried it and just couldn't get into it. If you wind up liking the series you should check out Lost Universe
. While it's in the Slayers universe it's something i enjoyed much, much more (as a sub fan i'll recommend the subs of course). A worty title to add to your list.
