Casting to casters! Good place to buy resin?

Did a quick search.. there are 7 pages of posts mentioning Alumilite in the Artists' subforum, possibly mostly not detailed but have a look and see if anyone compared notes and what they had to say about Alumilite products: http://www.denofangels.com/forums/search.php?searchid=5660654

 

Polyurethane resin is what you want for casting dolls. Alumilite sells polyurethane resin, as does Smooth-On. I tried to do a poll comparing the two (specifically for pinhole bubbles, which I've had problems with) here, but I'm not convinced that the sample size is large enough to be significant.

For "french" resin, you'll need transparent resin, dye, and some sort of filler. Smooth-On has an "amber" semi-transparent resin that I'm planning on trying; "water clear" polyurethane resin is more toxic. There are a lot of options for fillers: The Complete Sculptor's list

I like The Complete Sculptor because they actually come pretty close to living up to their name. You can find their list of rigid polyurethane resins (i.e., the kind of thing you can use to cast a doll) here. They have both Smooth-On and Alumilite, as well as their own brand.
