Stars! question

[Flare]

I have recently started playing the Stars! Demo, but I am very interested in getting a serial number to play the full game. My question is, where do I get one? I would not mind paying for it, but who has it & for how much? Or are there any other solutions to that problem?

Also, does anyone have any idea when Stars! Supernova Genesis is coming out, if ever?

Thanks for the info everyone!
