I think it's funny that the "non-cheesy" way to get experience for crafting involves a complicated set-up of some obscure magical nipple clamps from an evil book, an online magic item, a relatively obscure exalted spell, and using variable time planes. Everyone's definition of cheesy is different, I suppose
For another experience source (also cheesy), there's the item familiar feat. Could work well with the flavor of a crafter.
For a serious request, can you edit the lists to show which bonuses are applied in what order, and which don't stack? For example, if I make a +2 Longsword by myself (50% gold cost) reduction, make it only usable by CG characters (70% cost), requires 5 ranks in jump (90% cost), and have extraordinary artisan (75% reduction), does it cost 0% (or 0% plus 315g for the base masterwork sword)?
Or do you apply 50% to 8,000g for 4,000g, then apply 70%+90%=60% for 2,400g, then apply extraordinary artisan onto that for 1,800g (+315g for the base sword, or maybe less due to extraordinary crafter)? Or is it some other combination?
Every time I make a crafter (ok, BOTH times I made a crafter), I have to look this stuff to see whether the discount is to base cost, final cost, or what, and it drives me nuts.
Some simple crafter builds that don't necessarily focus entirely on crafting:Artificer 20
Binder 20 (Binds Astaroth)
Binder 10/Legacy Champion 10 (Combined with a good legacy item and/or item familiar, could be worthwhile)
Factotum 8/Chameleon 10/Master of Masks 1/Mindbender 1 (Chameleon floating feat for item creation)
Conjurer 3/Binder 1/Anima Mage 10/Knight of the Sacred Seal 5/Binder +1 (Binds Astaroth)
Conjurer 3/Binder 1/Anima Mage 10/Incantatrix 6 (Binds Astaroth)
Transmuter 5/Fleshwarper 10/Effigy Master 5 (Grafts and constructs specialist)
