I recently got the Nuclear Data set. I really like it, however, i would love to see an ISO enter "Activate" key for the set. I have sent a message to the designer of the Nuclear Data set about the legend.I want to have one made for myself,and i thought i might post here to see if other people also were interested in this.The key will also fit other SA sets out there, if you are interested in a contrast.Let say it would cost 10$ per for a start - i need to check this with Melissa over at Signature Plastics, but i am happy to pay all fees associated with this.
