Some of my favorite builds involve Sorcerer and some Prestige classes.
Sorcerer 6 / Incantatrix 10 / Abjurant Champion 4 (ends up with base attack of +20 with full casting levels after buffing)
Sorcerer 6 / Incantatrix 10 / Archmage 4 (metamagic extraordinaire)
Sorcerer 10 / Argent Savant 5 / Force Missile Mage 5 (magic missile is your bread and butter blasty spell)
Sorcerer 6 / Eldritch Knight 7 / Abjurant Champion 5 / Dragonslayer 1 / Spellsword 1 (natural base attack of +17 with 19 levels of sorcerer spellcasting)
Sure, Sorcerers and Wizards seem weak to start the game, but once they hit 6th level and can start flinging around iconic blasty spells, buffs, and debuffs they start turning into "gods". No joke, a well placed area of effect debuff, like slow, can turn a losing battle into a winnable battle instantly.
