Spontaneous Arcane Caster base classes

[thorr-kan]

Ignoring Dragons Magazine, ACF, and substitute levels, 3.5ED has the following spontaneous arcane casters?
Bard
Sorcerer
Beguiler
Dread Necromancer
Duskblade
Hexblade
Spellthief
Warmage

Dragonfire Adept (arguably)
Warlock (arguably)

Am I missing any?

[Honest Tiefling]

Hexblade and Spellthief come to mind.

A number of PrCs have independent spontaneous casting.

Are feats among the things you'd like to discount, and does Dragon Compendium count as Dragon Magazine? Because an arcane caster that can cast a cure or inflict spell (like a Death Master or a Wizard with the Destruction Domain) can take the Spontaneous Healer or Spontaneous Wounder feat and be able to spontaneously cast, which is good enough for some qualification purposes. This is probably more in the spirit of things you seem to be trying to avoid, like the Spontaneous Divination Wizard ACF, but it bears some mention.

For my purposes, Compendium is Magazine and base classes only.

[Thurbane]

Favored Soul can cast (some) of his spells as Arcane with the right feat(s), but I'm guessing not what you are looking for?

Are you limiting this list to Wizards of the Coast material? If not, you can technically add Shadowsworn, but it is not of great quality (http://www.giantitp.com/forums/showsinglepost.php?p=15033615&postcount=1).
