In terms of PrCs...
Eldritch Knight: This class has been made into a joke by other PrCs...
Waterdeep Specialist: From Waterdeep hardcover. Not the name of it, but it gets big hit dice regardless of core class. (It's like a template PrC). Errata may have fixed that.
Adjuration Champion: From Complete Mage. d10 hit dice, fighter's bab, full spellcasting at all levels plus special abilities. WFT?
Eldritch Knight w/Horse from one of the Eberron books. d8 hit dice, fighter's bab, I think almost full if not full spellcasting and special abilities related to their horse. Another WFT in comparission to the base set down by the Eldritch Knight which gets d6 hit dice, loses a level of spellcasting ability, generally requires you to multiclass and gives you no special abilities.
The mage blade from Arcana Evolved and the Dusk Blade from Player's Handbook II act as okay substitues for 'em.
