Recently, I started to expire with similar lvl on Edron Undead Cave. It is located to the northwest of the island. You can find Vampires, Necromancers and Bonebeasts there. You won't lose money on exp, due to the high prices of Vampire Teeth, not to mention the extra profits for the rest of the items. Exp / h is up to 200k.
Another interesting option is Ogres on Krailos. At this level, you still have to run a paladin so as not to get caught. It is worth getting the Dwarven Ring because of the ogres' ability to get you drunk. Exp / h is around 160k.
