M Jackson, I totally know how you feel. I wish stuff was a little less expensive but on the other hand I like to think I am doing my part to show support for not only Futurama but the merchandise as well. If people wait until retailers are forced to discount them before buying them retailers are less likely to order any new Futurama products because their preception is that Futurama doesn't sell and I have to discount them tremendously just to break even.
On the other hand, this like the tin wind-ups are sure to come down in price in a couple of months. Although, since I have not been seeing them in too many places it is always possible they underrun the production on them and they could be considered 'rare' in the future.
My advice as always is just to go out and purchase it. You like the show don't you?
