Also, avoid NuTech. Angels in the Court was probably my favorite of theirs, but while companies like Kitty and Central Park will give you several episodes (or possibly even the full series), NuTech will almost always just give you one twenty minutes episode. Kitty or Central Park also includes a really nice little introduction to adult anime on their discs that lets you know about some of the cultural differences. I've reviewed a few anime titles, so hopefully those help you find something you like.
