The Complete Divine has an optional turning rule, that inflicts damage to undead instead of turning them.
My players love it. The save DC for half damage is quite high, being DC 10 plus cleric level plus charisma modifier (usually the character level for such abilities' ST is divided by two, not so in this case).
The 4th level cleric IMC has but one magical item, and it's a Phylactery of Undead Turning. He also took the feats Quicken Turning, Empower Turning, and Extra Turning.
He did so because IMC, they are in a very undead prominent kingdom.
What this means in game terms is that when they face undead, he can as a free action inflict to all undead within 30 feet 12d6 damage, will save DC 22 for half damage. 10 times per day. At 4th level.
After a few more encounters with the undead forces of my world, I intend to make him a prime target of those forces, which will hire non-undead critters to go after him.
