Interesting question. I think the investment in Silver only /without writings on it/is a great deal, but regarding Silver76Pack is not a good idea for me. It's far away from SFI mission to build team for free. This is my opinion. One more thing - I can't sell it outside Tripleclicks amd SFI members. So for the moment I don't think to invest in it. But it's a great tool to show off for who wants to do it.
