Construct-building prestige classes?

[Arnwyn]

Does anyone know of any (and all!) prestige classes related to building constructs?

My Google-fu is pretty weak, and I could only find the Effigy Master (Complete Arcane). It doesn't matter what the source is (though priority would be WotC books...)

Thanks in advance to anyone who might know!

The Artificer base class (Eberron Campaign Setting) might fit the bill; although it's primarily related to crafting all types of magic items, Craft Construct is one of its bonus feat options.

There's always the base class from "iron Kingdoms" Arcane Mechanic. Although I think that is fully related to Steamjacks... I haven't read the source books in a while :/

Effigy Master, from Complete Arcane, pag. 30

Golem Master, from Kindoms of Kalamar Player´s Guide, pag. 55

I personally wouldn´t take a prestige class so focused in a single thing that is not so great but, if you do, I would combine levels of the Artificer Base Class with those two Pr.Classes plus the feats Improved Item Creation, Exceptional Artisan, Legendary Artisan, Reforge Magic Items and Quick Crafting, and also create some Dedicated Wright Homunculus (Magic of Eberron) and Pipes of Power (Book of Eldritch Might) in order to help me...
