I believe that most people on this forum would donate or allready have (I must say to my shame that I did not donated yet). In this forum are mostly hackers, coders or enthusiasts. Lots of Pandora buyers are just costumers. "Normal" people who don't want to donate but would buy raffle tickets. Every time at christmas it is the same. Almost nobody gives the poor guy sitting in the cold a coin, but everybody tries to win the big teddybear for his/her kid.
Why is the price attractive:
Lots of people have a rebirth or a cc unit. The ghz is sweet. Or they have somebody who could get it great christmas present. Or sell it. Or give it to the kids, so they have a CC unit and won't touch the ghz unit anymore. Or the tv out cable sounds nice, lots of people want one. I think the prices are attractive. Or maybe use gcw zeros, they are popular and not very expensive I think.
The legal concerns are a problem. Best would be, if LINK hosts the stuff (trustworthy, US) and just buys 2 Pandoras + TV Out cable with carry case, with the lottery money from ED. The profit will be send to ED.
Edit: Maybe sell the raffle tickets in links store. So people who are just interessted in a Pandora can buy them. But just one per person, don't let people ruin themself!
