I think it's a terrible set. They're packing in two duplicates already. You've got the Roman Auton, and a stone Roman Auton, which is nothing more than a new paint job. Then you've got the ugly Dalek, with a stone ugly Dalek, which again is nothing more than a new paint job. What's the point?
This is the kind of thinking that gives us a Destroyed Cassandra "action" figure.
