Did you talk to Chris? When I bought a set of New Old Stock Spinergy Tiliums from a Supergo-turned-Performance that was missing the spoke wrench, rim strips, and documentation, I emailed Spinergy and Chris responded. He sent the spoke wrench right away and said the Stealths were much better wheels and offered to upgrade my Tiliums for a fraction the cost of new. I kept the Tiliums.
He said he came in to replace the previous Customer Service director and basically "cleaned house". I can't say how their service was before, but it is A+ now.
