Demon Summoning PrC

[Ionbound]

Other than Thaumaturge, are there any good PrCs for summoning demons that don't have a silly racial restriction like demonbinder?

Malconvoker (CS, 48) is pretty sweet, and can probably fit in with what you're trying to do.

Malconvoker is pretty amazing. You Bluff demons and devils into aiding you, powering them up in the process. The later levels give you bonuses to Planar Binding spells, but my favorite thing is level 5 where you get an extra demon/devil whenever you summon them (effectively a free Twin Spell for your highest level summon, or Empower for a lower level one.)

Malconvoker (Complete Scoundrel, pp. 48-52), Nar Demonbinder (http://www.wizards.com/default.asp?x=dnd/ex/20030502a&page=2), and to a lesser degree Fiendbinder (Tome of Magic, p. 221-228) all spring to mind.

If Pathfinder materiel is allowed, Blackfire adept is decent (Paths of prestige)

I managed to get my GM to agree to Malconvoker. Thanks for giving me the nerve to ask around alignment restrictions, guys.
