Wiper Blade refills?

anyone know of a source for wiper blade refills for the factory arms? my wiper blades are shot, and I don't really want to put aftermarket black blade assemblies on my car, since my silver blades are still in great shape, the rubber is just toast. is this the only source? it looks like they should work....
