As for the "extra" units. They should be auctioned off internally and the proceeds should be split among all of us in proportion to how many we ordered out of the total. I hate lotteries... random shit sucks.
My vote is with them belonging to arklan, to do with as he pleases. Think what you will of that, but it's my vote for now.
+1 to them going to Arklan (after 6 months).
2nd choice is auction.
Hate lottery option.
If the 5 are over and above what is reasonable to have for guarantee work, I say give them to him now so he can sell them for a good price (or I should say, these absurd price which likely won't last for long.)
Seems to me that he's the guy who ran this show so it's legally and ethically right that the units are his outright. We would not even know about them but for his high level of communications and transparency.
