A NIB Stern is going to run you substantially more than $2500... so ticket prices would have to go up and I think you'll have an even harder time selling out.
I kinda like the idea of raffling off some quirky title. I think we should find a nice Raven
The winner always has the option to flip the game on kijiji or here if they don't like it; and the option to convert the winnings toward a NIB is a nice option too.
