Savage Species has a spell called Minor Servitor (p.68), which allows creation of moderately intelligent (friendly to the creator), permanent animated objects for an XP cost of 250 per cubic foot (an object up to 1 cubic foot/level may be animated); it's a 5th level Sor/Wiz spell. The contruct gets Int 3d6 and Cha 1d3. They behave as they wish and can reason and think on their own (within their Int score), but will obey their creator if specifically told to undertake actions. The spell takes 1 day to cast.
The Creature Collection II has a tiny construct called a "Totem of Mormo" that can store a single 3rd level spell in itself and cast it once. I would allow Minor Servitor to create Totems of Mormo.
Anyway, Minor Servitor allows you to create all the cute little animated objects in Disney's Beauty & The Beast, LOL, or maybe even the robots in A.I. if you're high enough level. You could make a fortune selling/renting out "Gentleman Jim" constructs to jaded aristrocrats!
You can use them as guards, spies or servants/slaves, or sell/gift them. A fun spell, much better than Animate Objects but it can't be used in combat with the 1 day casting time, and the XP cost limits the number of constructs you can make.
Golems are too expensive, IMO, or maybe my DM is just to stingy with the gold...
