Items for Turning Undead

[ZhanStrider]

So, Radiant Sphere from MIC lets you burn Turn undead attempts for some cool stuff. Are there any more items like this?

Are there any for Smite or Lay on Hands?

A Divine Wrath weapon (+1 bonus, MIC I believe) allows you to use a Turn attempt to gain extra damage based on your Charisma (1d6 damage per point of Charisma modifier). Only works on undead though.

The Shield of Mercy allows you to expend smites to heal other creatures.
