re: One group offers 5 payment of $30 plus shipping
I understand what you are saying. But, non of the plastic model companies would foot the costs of such a thing. CALTECH/JPL charges for the rights and there is not enough of a market for them to make a profit.
Remember Mattel made those action packs for Pathfinder and Sojourner and had huge sales. But I've heard they lost big time on action packs with Mars Polar Lander, Deep Space 2 probes and the Mars Climate Orbiter.
I'm a modeler so to be forced to buy an already assembled product is sort of a let down. All the fun is in the building the thing! Anyway, I did buy one.
