That's right on par for price for me, Jason, exchange rate included, and I pick mine up, as well.
I would recommend, before you crack all that open, about thinking about your armatures and coming up with ways to decrease how much clay you need for each sculpt. An example being my next hand sculpt. Though I built a solid armature for both hands, I will be going back and making a new one for my right hand. It will be constructed out of aluminum armature wire, attached to another pipe, and wrapped in foil to build up the mass and shape. this not only cuts down on how much clay I will need, but unlike the Ultra Cal form, I will be able to repose the fingers for a more "natural" mold and cast, after the sculpt is completed (Hopefully, hehehe). The use of foil can also be used in the creation of Pred heads. I really like how one member (Forget whom) glued a leftover bowl to the human head. Again, with the use of foil, clay use can be cut down even further. The point of all this is A) Sculptures will not be as heavy multiple projects can be started at once.
It's about damn time you started sculpting, you creative slacking *******!
