After my experience in Boston least year, where virtually every creator had an upcharge for CGC and a general sense of indignation towards fans requesting a signature or sketch, the SS program, to me, has lost most of its luster. It makes the creators ornery, even when they benefit financially, which in turn makes the fans feel like they are doing something wrong.
If I can't enjoy the creation of the collectible then I won't enjoy the owning of it, and thus the whole thing becomes pointless. Therefore, I've mostly moved on to spending my money elsewhere. I suppose the creators are getting what they want: no fat stacks for anyone.
