Hey Andrew cann't wait to see some photos. I get my epoxy from U.S. Composites, cann't find it cheaper anywhere else and seems to be a good product. For misc supplies, like wood flour, chopped glass, tape, etc I order from RAKA, but when you order, call Larry and ask what specials he has, generally he makes deal to move the last of an order or something he only has a small quantity left of. Generally if you don't have a specific product need something else will work and could save you a buck or two.
Good luck
