Doh. For some reason, I'd actually assumed d10s were cheats, no, I see they're perfectly fair (they're not platonic solids, but the shape is one of the valid face-symmetric results for a fair die).
However, I'm sure anything where the symmetry involves just one axis of rotation is a cheat, though inconveniently can't formalise that constraint. It works for seven, but it bugs me because it works for a 100 too, but isn't very elegant for that...
