It's strange that people would think these turning items are going to ruin an undead critter's ability to challenge the party. IME, they're necessary at high levels if there is any chance of the cleric turning undead at all. High CR undead like Nightwings and Nightcrawlers seem to have HD so far above their CR that clerics have no hope of turning them unless they are decked out with something like the kit suggested at the beginning of the thread... and carry a portable altar with the consecrate spell cast on it. Even low-HD undead are very very difficult to turn at high levels if they're bolstered (not that skeletons, zombies, etc pose much of a challenge by mid levels....but turning isn't effective against them). And if any of those undead are advanced, you might still have to forget about turning them.
