Glenn:
I ordered a sample kit from S3 early on. It was $15 (including shipping) and had 8 oz. of resin, a small bottle of hardner, 4 oz. of microballoons, 4 oz. of silica, 4 oz. of wood flour, 1 sf of cloth, a bunch of gloves, squeegees, brushes, mixing cups, and mixing sticks. It also had a copy of their "Epoxy Book" and a catalog. The microballoons have been more than enough for the few times I needed them and the wood flour has worked well when I needed to lighten the stuff I pulled out of my sander's dust bag. All of the other supplies were used up over time. You can order the kits right off their website.
