By the way, you have to click the picture of the orbit ball to order. You can't click the link. Guess this was really quickly put up.
I might buy one or two as memorabilia, and/or because they're fun to kick around. For $10.
Why does this product have to be discontinued

If you wanted a full game field of plastic and fabric, you'd need more than $1300. I can see demos doing "volunteer make a GUS ball" drives. At least it's a fraction of the price.
Does anyone notice that the green ball is called a "fuel cell"? That actually makes more "logical sense" than Supercell. You return an Empty Cell to the fueling station and it becomes a... bad thunderstorm? That never made sense to me. I guess it was originally going to be called a fuel cell.
