FWIW, I've got a used set of Sunshine hubs and a NOS set of Suntour Vx, and they only differ in the branding marks. This is true for all sorts of Suntour components, like Suntour Superbe Cranks and Sugino Mighty, etc. Recently, the Suntour branded components are costing more, so seeking out the Sunshine/Sugino/Dia Compe et al equivalents is sometimes substantially cheaper if one is not so worried about branding issues, although the market seems to be catching up on this.
