What resources do you have available? In particular, do you have Libris Mortis (LM)? There are a number of nice feats for undead hunters in there. I tend to agree with the previous posters that the only thing going for the Hunter of the Dead is its True Death ability.
Consider taking a ranger with favored enemy (undead) instead. Or maybe a ranger x/fighter 4 with Necropotent (LM, +4 damage to undead with selected weapon), Improved Favored Enemy (Complete Warrior, +3 bonus to damage against favored enemies), and Unquenchable Flame of Life (LM, gain favored enemy bonus against undead to saving throws against the extraordinary or supernatural abilities of undead creatures).
A ranger 15/fighter 4 could have a +17 bonus to damage rolls against undead creatures before taking in account Strength and weapon enhancement bonuses (+8 favored enemy, +3 Improved Favored Enemy, +2 Weapon Specialization, +4 Necropotent) and a +8 to saving throws against the extraordinary or supernatural abilities of undead creatures (Unquenchable Flame of Life).
Add a level of cleric, and you can take feats like Sacred Vengeance (LM and Complete Warrior, spend one turn undead attempt as a free action to add +2d6 to all melee damage rolls against undead, works great with Two-Weapon Fighting) and Spurn Death's Touch (LM, spend one turn undead attempt to heal ability damage or remove paralysis or a negative level caused by an undead creature).
