L.A.M.B. bars from Fabriconnection are a personal fave of mine, and Jessica scents with EO. Doodlebottoms also has three scents that are scented with EO -- they are listed separately from the ones that aren't. The Sweet Orange is one of my favorites.
I think Northern Essence has a few natural scents, too.
